I am having trouble getting route redistribution into ISIS working. It works from ISIS to BGP, but I can't get the opposite to show up. I am using IOS-XR
Network has 3 routers:
A----B----C
A and B have an isis connection B and C have a BGP connection
Router A has some 10.0.0.0 subnets that are shared with Rotuer B via ISIS. Router B is then passing these on to Router C with BGP, using the redistribute isis command.
Router C has a 192.168.56.0 subnet that is shared with Router B via BGP. Router B wants to share this with Router A via ISIS, but when I use the redistribute bpg command the route does not get added to the isis routes, and never shows on Router A.
I am not sure what I am doing wrong here.
Configuration for Router A (running IOS):
! trimmed, several interfaces with `ip router isis`
router isis
net 49.0000.0000.0000.0000.00
configuration for Router B (running IOS XR):
router isis 1
net 49.0000.1111.0000.0000.00
distribute bgp-ls
address-family ipv4 unicast
redistribute bgp 65000 level-1

On Router C running show route bgp lists all of the routes from ISIS on A and B.
On Router B running show route isis shows all of the ISIS provided routes I expect, and running show route bgp shows the 192.168.56.0 route that I expect from C
On Router A the 192.168.56.0 route does not exist.
