锐捷BGP等价路由组网
我们知道BGP路由默认会自动学习最优路由，无法等价的，那么我们通过BGP等价路由条目可以实现BGP等价路由的效果。
一 网络拓扑
如上图：
Leaf1和Spine1和Spine2建立IBGP，Border1和Spine1和Spine2建立EBGP；
二 设备配置
2.1 BGP等价路由配置命令
配置命令：
Leaf1(config)#rou bgp 100
Leaf1(config-router)#address-family ipv4
Leaf1(config-router-af)#maximum-paths ?
ebgp EBGP-multipath
ibgp IBGP-multipath
Leaf1(config-router-af)#
Leaf1(config-router-af)#maximum-paths ibgp ?
<1-32> Number of paths
Leaf1(config-router-af)#maximum-paths ibgp 32
Leaf1(config-router-af)#maximum-paths ebgp 32
Leaf1(config-router-af)#
2.2 Leaf1配置bgp等价路由
!
router bgp 100
bgp router-id 6.6.6.1
bgp log-neighbor-changes

bgp graceful-restart stalepath-time 360

neighbor 6.6.6.2 update-source Loopback 0
neighbor 6.6.6.3 remote-as 100
neighbor 6.6.6.3 update-source Loopback 0
address-family ipv4
maximum-paths ebgp 32
maximum-paths ibgp 32
network 6.6.6.6 mask 255.255.255.255
neighbor 6.6.6.2 activate
neighbor 6.6.6.3 activate
exit-address-family
!
2.3 Spine1、Spine2、Border同样配置
!
router bgp 100
address-family ipv4
maximum-paths ebgp 32
maximum-paths ibgp 32
!
