Hi all,
Now I need a feature, I have to import neighbor as vlink route into bgpd.
So I use static route like this:
vtysh
ip route 1.1.1.1/32 Vlan100
redistribute static route-map XXX
But I encounter a problem:
before I add static route, there are B route like this:
B 2.2.2.100/32 [20/0] via 100.0.28.231, Ethernet52, src 1.1.1.230, 3d03h18m
after I add static route, there are two route like this:
S>* 2.2.2.100/32 [1/0] is directly connected, Vlan100
B 2.2.2.100/32 [20/0] via 100.0.28.231, Ethernet52, src 1.1.1.230, 3d03h18m
after I redistribute, there are only one route like this:
S>* 2.2.2.100/32 [1/0] is directly connected, Vlan100
But what I need is to keep two route.
Because if there is only one route, I have to relearn B route after I delete static route, which will cause package loss in long time(like 20 second).
For some producer like huawei, thay have 'import route' command, which will combine redistributed route and learned route, like this:
So will FRR support this feature ?
How to import route and NOT withdraw existing route ?
