Nexus Routing Question - MP-BGP VPNV4

May i know why the show forwarding route show "null0" for next hop?

though show routing shows "172.22.22.1' as next hop. 172.22.22.1 is in the global routing table.

whereas 192.168.200.20 is in VRF-1.

 

LAB3XSW0055-VDC-CDOQ-Golf-2-Chassis-1# show routing 192.168.200.20 vrf VRF-1
IP Route Table for VRF "VRF-1"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>

192.168.200.0/24, ubest/mbest: 1/0
*via 172.22.22.1%default, [200/0], 1d20h, bgp-65000, internal, tag 65033

=======================

 

 

Chassis-1# show forwarding route 192.168.200.20 vrf VRF-1

slot 1
=======


IPv4 routes for table VRF-1/base

'*' denotes recursive route
----------------+----------------------------------------+----------------------
+-----------------
Prefix | Next-hop | Interface
| Labels
----------------+----------------------------------------+----------------------
+-----------------
*192.168.200.0/24 0:: Null0
PUSH 37

 

 

Please advise.

Re: Nexus Routing Question - MP-BGP VPNV4

What platform is this from and what NX-OS version?

Looks like for the VRF-1 there has been no traffic forwarded so that table hasn't been populated yet.

How is this device connected in the network? Also on the other end of the link are you seeing the same results?

Re: Nexus Routing Question - MP-BGP VPNV4

Thank for your reply.

This issue is resolved.



I was doing MPLS BGP VPNV4 on underlay of static routing with ldp .

I changed the underlay routing to IGP between MPLS peers , the routing started working.
