Hi @NetworkSupport65408 ,

"show bgp vrf Vrf-name" only shows the address family ipv4 unicast by default. It appears that address-family ipv4 unicast is not configured for this vrf under BGP. Please check your BGP configuration.

  Thank you for your respose. Below is my configuraition for BGP and VRF.

Hi @NetworkSupport65408 ,

Try using the following command instead:

show bgp vpnv4 unicast vrf <VRF Name>

Hi @Harold Ritter,

       With this commond it show me the routes learned from IBGP neighbors which i have learned through address family vpnv4. My problem is, EBGP is not comming up with CE routers although point to point is pingable and there is no firewall between the PE and CE routers.

I have VRFs in same routers for which i am using the commond show bgp vrf <vrf name> summay and i can see for other customer the BGP is up.

But when i am configuring new vrf it give me this error.

Hi @NetworkSupport65408 ,

To check why the neighbor is not coming up, please use the following command:

show bgp vrf <VRF Name> neighbor <neighbor address>

Also make sure that you use the VRF name exactly as configured (It is case sensitive). If you don't this could also be the cause for the error message you initially reported.

Hi @Harold Ritter 

VRF name is correct and when i chagne the VRF name for testing, the BGP came up but when i returning back the VRF name the status still remain same.

When i further analyse i check below data. 

Switch name #show bgp vrf-db vrf <vrf-name>

VRF: <vrf-name>
RD: <IP:VLAN>
VRF ID: 0x0
RSI Handle: 0x55262698
Refcount: 4
AFs: IPv4 Unicast

How i can remove the vrf name  and RD from vrf-db. First time when i was configuring VRF, by mistake i give the wrong RD values. So when i delete the VRF and all the configuration related to VRF. it still show the VRF name and RD valaue in vrf-db.

Hi @NetworkSupport65408 ,

Thanks for the additional information. It looks like you might have hit a bug.

Normally, removing the vrf config under bgp and reapplying it with the new RD value should be sufficient.

router bgp <asn>

no vrf <vrf name>

commit

vrf <vrf name>

rd <new rd value>

commit

if this doesn't work for you, I would suggest opening a TAC case.
