mdc-admin
Parameters
route-policy-name: Specifies a routing policy name, a case-sensitive string of 1 to 63 characters.
deny: Specifies the deny match mode for the routing policy node. If a route matches all the if-match clauses of the node, it is denied without being compared with the next node. If a route does not match any if-match clauses of the node, the route is compared with the next node.
permit: Specifies the permit match mode for the routing policy node. If a route matches all the if-match clauses of the node, it is handled by the apply clauses of the node. If a route does not match any if-match clauses of the node, the route is compared with the next node.
node node-number: Specifies a node number in the range of 0 to 65535. A node with a smaller number is matched first.
Usage guidelines
Use a routing policy to filter routing information. A routing policy can contain several nodes and each node contains a set of if-match and apply clauses. The if-match clauses define the match criteria of the node and the apply clauses define the actions to be taken on packets matching the criteria. The relation between the if-match clauses of a node is logical AND. All the if-match clauses must be met. The relation between nodes is logical OR. A packet passing a node passes the routing policy. If a packet does not pass any nodes, the packet does not pass the routing policy.

Parameters
prefix-list-name: Specifies an IPv4 prefix list name, a case-sensitive string of 1 to 63 characters.
index index-number: Specifies an index number for an IPv4 prefix list item, in the range of 1 to 65535. An item with a smaller index number is matched first. If you do not specify this option, the index number starts from 10 and increments by 10 for each of the consecutive prefix list items.
deny: Specifies the deny mode. If a route matches the item, the route is denied without being compared with the next item. If a route does not match the item, the route is compared with the next item.
permit: Specifies the permit mode. If a route matches the item, it passes the IPv4 prefix list. If a route does not match the item, the route is compared with the next item.
ip-address mask-length: Specifies an IPv4 prefix and mask length. The value range for the mask-length argument is 0 to 32.
greater-equal min-mask-length, less-equal max-mask-length: Specifies a prefix length range. The greater-equal keyword means "greater than or equal to" and the less-equal keyword means "less than or equal to." The prefix length range relation is mask-length <= min-mask-length <= max-mask-length <= 32.
· If only the min-mask-length argument is specified, the prefix length range is [ min-mask-length, 32 ].
· If only the max-mask-length argument is specified, the prefix length range is [ mask-length, max-mask-length ].
· If both the min-mask-length and max-mask-length arguments are specified, the prefix length range is [ min-mask-length, max-mask-length ].
Usage guidelines
An IPv4 prefix list is used to filter IPv4 addresses. It can contain multiple items, each of which specifies a range of IPv4 prefixes. The relation between the items is logical OR. If an item is passed, the IPv4 prefix list is passed. If no item is passed, the IP prefix list cannot be passed.
If both the ip-address and mask-length arguments are specified as 0.0.0.0 0, only the default route will be matched.
To match all routes, use 0.0.0.0 0 less-equal 32.
Examples
# Configure IP prefix list p1 to permit routes destined for network 10.0.0.0/8 and with mask length 17 or 18.

ipv6-address: Specifies the next hop IPv6 address.
Usage guidelines
If you use this command to set a next hop for redistributed routes, the configuration does not take effect.
Examples
# Configure node 10 for routing policy policy1 to set next hop 3ffe:506::1 for IPv6 routes matching AS path list 1.
<Sysname> system-view
[Sysname] route-policy policy1 permit node 10
[Sysname-route-policy-policy1-10] if-match as-path 1
[Sysname-route-policy-policy1-10] apply ipv6 next-hop 3ffe:506::1
display ipv6 prefix-list
Use display ipv6 prefix-list to display IPv6 prefix list statistics.

Parameters
address: Matches the destination address of IPv6 routes.
next-hop: Matches the next hop of IPv6 routes.
route-source: Matches the source address of IPv6 routes.
acl ipv6-acl-number: Specifies an IPv6 ACL by its number. The value range for the ipv6-acl-number argument is 2000 to 3999 for the address keyword, and 2000 to 2999 for the next-hop and route-source keywords.
prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters.
Examples
# Configure node 10 of routing policy policy1 to permit routes whose next hop matches IPv6 prefix list p1.
<Sysname> system-view
[Sysname] route-policy policy1 permit node 10
[Sysname-route-policy-policy1-10] if-match ipv6 next-hop prefix-list p1
ipv6 prefix-list

Parameters
prefix-list-name: Specifies an IPv6 prefix list name, a case-sensitive string of 1 to 63 characters.
index index-number: Specifies an index number for an IPv6 prefix list item, in the range of 1 to 65535. An item with a smaller index number is matched first. If you do not specify this option, the index number starts from 10 and increments by 10 for each of the consecutive IPv6 prefix list items.
deny: Specifies the deny mode. If a route matches the item, the route is denied without being compared with the next item. If a route does not match the item, the route is compared with the next item.
permit: Specifies the permit mode. If a route matches the item, it passes the IPv6 prefix list. If a route does not match the item, the route is compared with the next item.
ipv6-address: Specifies an IPv6 address.
prefix-length: Specifies the IPv6 prefix length. The value range for the prefix-length argument is 0 to 128.
greater-equal min-mask-length, less-equal max-mask-length: Specifies a prefix length range. The greater-equal keyword means "greater than or equal to" and the less-equal keyword means "less than or equal to."
The prefix length range relation is mask-length <= min-mask-length <= max-mask-length <= 128.
· If only the min-prefix-length argument is specified, the prefix length range is [ min-prefix-length, 128 ].
· If only the max-prefix-length argument is specified, the prefix length range is [ prefix-length, max-prefix-length ].
· If both the min-prefix-length and max-prefix-length arguments are specified, the prefix length range is [ min-prefix-length, max-prefix-length ].
inverse inverse-prefix-length: Matches IPv6 addresses from the least significant bit to the specified length. The value range for the inverse-prefix-length argument is 1 to 128.
Usage guidelines
An IPv6 prefix list is used to filter IPv6 addresses. An IPv6 prefix list can have multiple items, and each of them specifies a range of IPv6 prefixes. The relation between the items is logical OR. A route passing an item passes the IPv6 prefix list. A route passing no item does not pass the IPv6 prefix list.
If the ipv6-address prefix-length argument is specified as :: 0, only the default route matches.
To match all routes, configure :: 0 less-equal 128.
Examples
# Permit IPv6 addresses with a mask length between 32 bits and 64 bits.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc permit :: 0 greater-equal 32 less-equal 64
# Deny IPv6 addresses with a prefix 3FFE:D00::/32 and a prefix length greater than or equal to 32 bits.
<Sysname> system-view
[Sysname] ipv6 prefix-list abc deny 3FFE:D00:: 32 less-equal 128
