SD-WAN Propogating Community

[georgehewittuk1]

Hi,

I am not seeing a community value set propogate across to other vEdges. I have service vpns configured with BGP redistruting with OMP.

vEdge Branch 3 for example -

BR-vEdge3# show bgp routes 172.16.31.0/24 detail
bgp routes-table vpn 1 172.16.31.0/24
best-path 1
info 0
nexthop 192.168.30.33
metric 0
weight 0
origin igp
as-path 300
ri-peer 192.168.30.33
ri-routerid 172.16.234.3
community 1234:1
path-status valid,best,external

Community 1234:1 set and then looking at vEdge 1 across the deployment the community is not there. Is this supported?

HQ-vEdge-1# show bgp routes 172.16.31.0/24 detail
bgp routes-table vpn 1 172.16.31.0/24
best-path 1
advertised-peers 0
peer-addr 192.168.11.11
info 0
nexthop 0.0.0.0
metric 1000
local-pref 50
weight 0
origin incomplete
as-path 300
ri-peer 0.0.0.0
ri-routerid 1.1.1.1
local true
sourced true
ext-community SoO:0:1
path-status valid,best
tag 0

Thanks!

George

Hi,

looks like this feature is introduced only for cEDGEs not for vEDGEs.  IOS XE 17.3.x release notes includes this feature:

https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/routing/ios-xe-17/routing-book-xe/m-unicast-routing.html#concept_jhq_r4p_13b

But in vEDGE 20.3.x release notes, this feature is not introduced.

HTH,
