Why show ip protocol vrf gives bgp by default in the output

[balaboi82]

When I give show ip protocol vrf the output is showing bgp even though bgp is not associated to the vrf

vrf config

ip vrf sprint-test
 rd 1.1.1.1:22
!

Hi,

Because that command output is for vpn and forwarding vrf instances. So it takes bgp... if bgp is configured on the router.....

Thanks Karthik.

Is there an alternate way to check what protocols are associated with a particular VRF?

We can use show run vrf <vrf name> but I need something without using show run

Hi,

It will show if you have mapped that vrf to a different protocol..... also... but in your case you have created vrf sprint-test and you have taken show output for vrf test..... if that vrf is not mapped to any protocols and if bgp exists it will show bgp as default..... if you have used it in someother protocols, then definitely it will show that info as well as bgp.....

Test output:

Sorry I copied the wrong vrf.

I understand show ip proto vrf gives all the protocols along with BGP by def but I wanted to know if there is an alternate to show run vrf.

If I run show run vrf vrf-test it will provide only protocols which the vrf is configured to. It will not show BGP if it is not explicitly attached.
