BGP路由汇总

把R1产生的路由跟R2产生的路由通过R3汇总为一条路由发布到R4

拓扑图如下图

R1

interface LoopBack0
 ip address 192.168.1.1 255.255.255.0 
#
interface LoopBack1
 ip address 192.168.2.1 255.255.255.0 
#
bgp 1
 peer 10.1.13.3 as-number 3 
 #
 ipv4-family unicast
  undo synchronization
  network 192.168.1.0 
  network 192.168.2.0 
  peer 10.1.13.3 enable

R2

interface LoopBack0
 ip address 192.168.3.1 255.255.255.0 
#
interface LoopBack1
 ip address 192.168.4.1 255.255.255.0 
#
bgp 2
 peer 10.1.23.3 as-number 3 
 #
 ipv4-family unicast
  undo synchronization
  network 192.168.3.0 
  network 192.168.4.0 
  peer 10.1.23.3 enable

R3

bgp 3
 peer 10.1.13.1 as-number 1 
 peer 10.1.23.2 as-number 2 
 peer 10.1.34.4 as-number 4 
 #
 ipv4-family unicast
  undo synchronization
  aggregate 192.168.0.0 255.255.248.0 as-set detail-suppressed 
  peer 10.1.13.1 enable
  peer 10.1.23.2 enable
  peer 10.1.34.4 enable

as-set  表示集成明细路由的AS_path

detail-suppressed 表示抑制明细路由

R4

bgp 4
 peer 10.1.34.3 as-number 3 
 #
 ipv4-family unicast
  undo synchronization
  peer 10.1.34.3 enable

当R4的BGP路由表只出现医疗路由时说明配置成功
