A Cisco 1941 router not bringing up a VRF on a ISP router

GlynnNewey0470

At one of our sites we have our own router Cisco 1941 router connected to an ISP router also Cisco as happens

 

I can remote onto our 1941 router using its wan IP no issues there

 

But when I connect through our management loop back address I am getting no response back (within our organization)

 

Our 1941 router has a 8 port switch card (the site only has a few pc's and devices), because of this there is not always a live device to keep the VRF it uses up

 

Is there a way of keeping a VRF up even when there are no live devices connected at a certain time

 

Cheers

Hello,

As I remember the old command You can try VLAN auto state up (not sure if this works on the router - been used a long time

 

inter  vlan 100 (example)
no autostate

 

or 

 

interface Gi0/0

no keepalive

 

or post the complete config and what option you have on router. and show version.

This is how the vrf is setup

 

Configuration Template Version 5.2

 

interface Loopback0
ip vrf forwarding Network_Data
ip address x.x.x.x 255.255.255.255
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress

 

 

interface GigabitEthernet0/0
description link to ISP
ip address x.x.x.x 255.255.255.252
duplex auto
speed auto
crypto map mymap

Hello

So internally you cannot access the 1941 RTR correct?

That is right internally we can not access the 1941 router, we don't always have active devices on the 1941 switch module so assuming its because of that why we can't see the router internally. Its not bringing the VRF up when there are no devices.

Can you post the configuraition#

Hello

Usually the rtr would be connected to a handoffL3 switch or firewall that has a designated vlan port or dmz for mgt, So without understanding your topology it would be hard to suggest anything.

Can you elaborate further on how this rtr is connected or maybe even post a diagram with the running config of the 1941?
