Running BGP health test on switch without multi-agent

[kosichd]

On switches that do not have "service routing protocols model multi-agent" configured, the cmd "show bgp {afi} {safi} summary is not supported. When using VerifyBGPSpecificPeers or VerifyBGPHealth tests, it seems to only work if the switch in question is using mulit-agent. For switches that have "service routing protocols model ribd" configured, there should be a way for the test to run "show ip bgp sum'

It seems the problem may be here, as "show bgp {afi} sum' is not a valid EOS command:

commands: ClassVar[list[AntaCommand | AntaTemplate]] = [
    AntaTemplate(template="show bgp {afi} {safi} summary vrf {vrf}", revision=3),
    AntaTemplate(template="show bgp {afi} summary", revision=3),

From a switch running 4.31.5M, 'summary' is not an option

switch#sh bgp ipv4 ?
access-list Named access-list
labeled-unicast Display labeled-unicast information
multicast Display multicast information
unicast Display unicast information

Also from a switch not running multi-agent:

switch#sh bgp ipv4 unicast sum
% Not supported

Hi @kosichd,

These tests are indeed only supported on switches running with multi-agent. Multi-agent has been the default since 4.30.1, and starting with 4.32, you cannot configure ribd at all. Therefore, we don't have any plans to support ribd for these tests.

The show bgp {afi} summary command template is only used when the AFI is not IPv4 or IPv6 (e.g., evpn, vpn-ipv4, etc.). VRF is not needed here since these AFIs operate at a global level and do not use the VRF concept in the same way as IPv4/IPv6. On the other hand, show bgp {afi} {safi} summary vrf {vrf} template is used with IPv4 and IPv6 AFIs, where a SAFI is also needed with an optional VRF.

We have simpified the logic of this in PR #888, where we now use show bgp summary vrf all and show bgp neighbors vrf all commands instead, without impacting test inputs.

Thanks for the quick reply @carl-baillargeon

Anytime @kosichd. I will add a note in our documentation around this.

Thanks!

The goal for this one would be to write two new tests in parallel of VerifyBGPSpecificPeers or VerifyBGPPeersHealth tailored for RIBD with new names (because they require different commands).

The documentation warning needs to be updated
