Cisco 2800 Series Router Frame Relay Issue
So we have in place a Cisco 2610 router that connects our main site to 4 of our other sites via IETF point-to-point frame relay connections.
The router has a Serial WIC card in it to handle these connections and the configuration for it is at follows.
interface Serial0/0
no ip address
encapsulation frame-relay IETF
frame-relay lmi-type ansi
Now in order to do the point to point I have 4 sub interfaces configured, they are as follows
interface Serial0/0.1 point-to-point
description *** Site 1 ***
ip address 150.104.1.1 255.255.0.0
frame-relay interface-dlci 104
!
interface Serial0/0.2 point-to-point
description *** Site 2 ***
ip address 150.201.1.1 255.255.255.0
frame-relay interface-dlci 201
!
interface Serial0/0.3 point-to-point
description *** Site 3 ***
ip address 150.102.1.1 255.255.255.0
frame-relay interface-dlci 102
!
interface Serial0/0.4 point-to-point
description *** Site 4 ***
ip address 150.105.1.1 255.255.255.0
frame-relay interface-dlci 105
The problem i'm having is that we are switching over to a new Cisco 2800 series Router that is replacing the old 2610.
So I unboxed the 2800, did the configuration line for line the same as the old one, put it in place and switched the cables. Everything immediately came back up except for SITE 4.
For whatever reason, even though the config looks IDENTICAL and all the other sites immedately come back up, Site 4 does not.
The router at site 4 is also a 2610, the config on it for the Serial WIC looks like this
interface Serial0/0
no ip address
encapsulation frame-relay IETF
service-module t1 timeslots 1-4
frame-relay lmi-type ansi
bridge-group 1
and the subinterface that connects back to the main site looks like this
interface Serial0/0.1 point-to-point
description *** Main ***
ip address 150.106.1.2 255.255.255.0
frame-relay interface-dlci 200
bridge-group 1
This router was put in long before i got here so i'm not sure if all the stuff in the config actually needs to be there or not but i figured it was hurting anything so i better just leave it alone.
If i do a show frame-relay pvc it says that the connection for Site 4 is configured, but INACTIVE.
I cannot figure out for the life of me why it won't come up like the other 4. Is there some command that you can use to manually activate a frame relay PVC?

Difficult to say without a bunch more information (like the full output of the "show frame pvc" command).
Could be the Site 4 PVC doesn't go to your main site but to one of the other remote locations. This seems likely given that the IP addresses on your main router are not consistent with the address at site 4.

Wierd thing is it says inactive on this end but it still seems to be connected and I can still ping everything over at that site. why would one side be active and the other inactive?
