gRPC server configuration for eXR 6.6.3 on asr9k

[patoh]

Hello All,

Could anyone suggest what is the proper way to enable gRPC server on asr9k running IOSXR 6.6.3 64-bit?

My setup:

asr9k router - {other routers} - servers running VM with telegraf docker

- VM is able to reach asr9k Loopback in VRF (ping/ssh)

- gRPC connection times out from telegraf and also telnet/nc test from VM to asr9k IP:port times out

asr9k config:

#sh run int lo10
interface Loopback10
 vrf test1
  ipv4 address 10.0.0.10 255.255.255.255


#sh run tpa
tpa
 vrf test1
  address-family ipv4
   update-source dataports Loopback10
!

#sh run grpc
grpc
 vrf test1
 port 57777
 no-tls
 address-family ipv4
!

I don't see asr9k listening on tcp/57777

#sh tcp brief | i 5777
#

telnet tcp/57777 from VM:

$ nc -vz 10.0.0.10 57777
nc: connect to 10.0.0.10 port 57777 (tcp) failed: Connection timed out

Is something wrong with the config? something missing? any suggestions?

thanks

I got confirmation from Cisco Engineer that this setup gRPC in VRF is not fully supported at the moment.

there are two workarounds:

1) use gRPC server in VRF using MGMT port as source interface, collector also has to be reachable via MGMT interface.

there might be some feature/scaling limitations so consult with cisco if you want to deploy it this way.

2) use gRPC in GRT -> this is fully supported and there should be no limitations.
