1  简介

本文档介绍DRNI特性的配置举例。

DRNI是一种跨设备链路聚合技术，将两台物理设备在聚合层面虚拟成一台设备来实现跨设备链路聚合，从而提供设备级冗余保护和流量负载分担。

2  配置前提

本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解DRNI特性。

3  基于接入层的DRNI配置举例

3.1  组网需求

如图1所示，Device A和Device B为接入设备，Device C和Device D为网关设备。现要求使用DRNI技术实现接入设备的冗余保护和流量负载分担功能。具体要求如下：

·     在Device A和Device B上部署DRNI，实现接入设备的冗余备份和流量负载分担。

·     分别在Device A和Device B上配置保留接口，用于DRNI主备设备间Keepalive报文的传输，检测Device A和Device B是否故障。

·     在Device C和Device D上部署VRRP，当网关设备工作正常时，区域A用户通过网关设备Device C进行数据转发；区域B用户通过网关设备Device D进行数据转发，实现流量的负载分担。

·     当Device C或者Device C的上行接口发生故障后，Device D能够迅速承担区域A内主机流量的转发任务；Device C故障恢复后，继续承担VRRP备份组1的网关功能。

·     当Device D或者Device D的上行接口发生故障后，Device C能够迅速承担区域B内主机流量的转发任务；Device D故障恢复后，继续承担VRRP备份组2的网关功能。

·     在Device C、Device D和Device E上搭建OSPF网络，Device C和Device D通过OSPF发布区域A和区域B内的主机所在网段的路由，以实现区域A和区域B内的主机与外部网络的三层互通。

设备	接口	IP地址	设备	接口	IP地址
Device A	HGE3/0/5	1.1.1.1/24	Device B	HGE3/0/5	1.1.1.2/24
Device C	Vlan-int100	100.1.1.1/24	Device D	Vlan-int200	200.1.1.1/24
	Vlan-int10	10.1.1.1/24		Vlan-int10	10.1.1.2/24
	Vlan-int20	20.1.1.1/24		Vlan-int20	20.1.1.2/24
	Virtual IP 1	10.1.1.100/24		Virtual IP 1	10.1.1.100/24
	Virtual IP 2	20.1.1.100/24		Virtual IP 2	20.1.1.100/24
Device E	Vlan-int100	100.1.1.2/24
	Vlan-int200	200.1.1.2/24
	Vlan-int30	30.1.1.1/24

 

3.2  配置思路

·     分别在Device A和Device B上配置保留接口的IP地址，且保证能够三层互通，用于DRNI主备设备间Keepalive报文的传输。

·     为了让Device C和Device D分别成为VRRP备份组1和VRRP备份组2中的Master，需要在VRRP备份组1中为Device C配置较高的优先级，在VRRP备份组2中为Device D配置较高的优先级。

3.3  配置注意事项

配置DRNI时，需要注意：

·     要求所有DR设备配置相同的系统MAC地址和系统优先级，配置不同的系统编号。

·     一台DR设备上只能配置一个IPP口。

·     建议用户将Keepalive接口配置为保留接口，避免在DRNI建立过程中被置为MAD DOWN状态，造成错误检测。

配置VRRP时，需要注意：

·     VRRP备份组的虚拟IP地址不能为全零地址（0.0.0.0）、广播地址（255.255.255.255）、环回地址、非A/B/C类地址和其它非法IP地址（如0.0.0.1）。

·     建议将备份组的虚拟IP地址和备份组中设备下行接口的IP地址配置为同一网段，否则可能导致局域网内的主机无法访问外部网络。

4  基于汇聚层的DRNI配置举例

4.1  组网需求

如图2所示，Device A和Device B为汇聚层设备，通过在Device A和Device B上部署DRNI和VRRP，可以满足以下要求：

·     当Device A侧链路发生故障时，流量可以快速切换到Device B侧链路，保证可靠性。同时为了高效利用带宽，Device A和Device B侧链路可以同时转发报文，实现负载分担。

·     在网关设备工作正常时，区域A用户通过网关设备Device A进行数据转发；区域B用户通过网关设备Device B进行数据转发，实现流量的负载分担。

·     当Device A或者Device A的上行接口发生故障后，Device B能够迅速承担区域A内主机流量的转发任务；Device A故障恢复后，继续承担VRRP备份组1的网关功能。

·     当Device B或者Device B的上行接口发生故障后，Device A能够迅速承担区域B内主机流量的转发任务；Device B故障恢复后，继续承担VRRP备份组2的网关功能。

·     在Device A、Device B和Device E上搭建OSPF，Device A和Device B通过OSPF发布区域A和区域B内的主机所在网段的路由，以实现区域A和区域B内的主机与外部网络的三层互通。

图2 基于汇聚层的DRNI配置组网图

 

设备	接口	IP地址	设备	接口	IP地址
Device A	HGE3/0/5	1.1.1.1/24	Device B	HGE3/0/5	1.1.1.2/24
	Vlan-int100	100.1.1.1/24		Vlan-int100	100.1.1.2/24
	Vlan-int101	101.1.1.1/24		Vlan-int101	101.1.1.2/24
	Vlan-int10	10.1.1.1/24		Vlan-int20	20.1.1.1/24
	Virtual IP 1	100.1.1.100/24		Virtual IP 1	100.1.1.100/24
	Virtual IP 2	101.1.1.100/24		Virtual IP 2	101.1.1.100/24
Device E	Vlan-int10	10.1.1.2/24
	Vlan-int20	20.1.1.2/24
	Vlan-int30	30.1.1.1/24

 

4.2  配置思路

·     分别在Device A和Device B上配置保留接口的IP地址，且保证能够三层互通，用于DRNI主备设备间Keepalive报文的传输。

·     为了让Device A和Device B分别成为VRRP备份组1和VRRP备份组2中的Master，需要在VRRP备份组1中为Device A配置较高的优先级，在VRRP备份组2中为Device B配置较高的优先级。

4.3  配置注意事项

配置DRNI时，需要注意：

·     要求所有DR设备配置相同的系统MAC地址和系统优先级，配置不同的系统编号。

·     一台DR设备上只能配置一个IPP口。

·     建议用户将Keepalive接口配置为保留接口，避免在DRNI建立过程中被置为MAD DOWN状态，造成错误检测。

配置VRRP时，需要注意：

·     备份组的虚拟IP地址不能为全零地址（0.0.0.0）、广播地址（255.255.255.255）、环回地址、非A/B/C类地址和其它非法IP地址（如0.0.0.1）。

·     建议将备份组的虚拟IP地址和备份组中设备下行接口的IP地址配置为同一网段，否则可能导致局域网内的主机无法访问外部网络。
