VPNV4 AF 不传路由 – IOSXRv

两台ASBR之间建立了EBGP VPNV4的邻居关系。邻居关系没问题,但是无法收发路由,路由为0且后面有一个叹号。报错如下:

Some configured eBGP neighbors (under default or non-default vrfs)
do not have both inbound and outbound policies configured for VPNv4 Unicast
address family. These neighbors will default to sending and/or
receiving no routes and are marked with '!' in the output below.

这是由于对EBGP邻居没做入向和出向的路由策略造成的。增加route-policy,并在BGP进程下neighbor对端的时候调用后,这个小叹号和报错就没有了。
