Hi Community ,
I am having asr1001 & added the following config for bgp
ip vrf 250
interface Port-channel1.250

Networks under bgp with network command are not advertising to Neighbour.

network 10.220.0.0 mask 255.255.255.0
Do I am missing any configuration for VRF 250 please?
Whats the config I am really missing here ?
Thank you ..

Check link how to leak between vrf and global
Also vrf you config is missing RD

Thank you, I added the following configurations but still asr1001 not advertising
I like to advertise the network 10.50.120.0/24 connected directly on asr1001
Following is the configurations; can you please tell what I am missing in the following configurations?

router bgp 65133
Redistrubte connect <<- since SVI in global we will redistrubte it into global bgp' and bgp will import these prefix into vrf 250
address-family ipv4 vrf 250
redistribute connected route-map VRF-Global-to-VRF-250 <<- no need this we use import map for global to vrf
You will face other issue which is from svi to any prefix learn from vrf 250' this solve by
Ip route vrf x.x.x.x/× <next-hop> global
Try above and check
