P.S. Cisco IOS-XE平台验证对等体是否支持软刷新,使用show ip bgp neighbors就可以了,Capalities里会显示出来—— Neighbor capabilities: Route refresh: advertised and received(new) 不过,在实际的实验中,我发现Soft Reset并不是一个立即生效的特性,而且无论是你等路由器自动刷新还是手动Clear,它总有一个最长30...
觀察到,在R3上,debug命令debug bgp ipv4 unicast已啟用。 為了進一步確認未收到路由,會執行命令clear bgp ipv4 unicast * soft,強制再次交換路由。R3路由沒有收到該路由。 R3 - Cisco IOS® R3#debug bgp ipv4 unicast BGP debugging is on for address family: IPv4 Unicast ...
