Hi,
Eigrp or OSPF networks are not advertise on FR links on PPP Virtual templete. Please help.
R4(config)#int virtual-template 1
R4(config-if)#ip address 141.141.45.4 255.255.255.0
R4(config-if)#exit
R4(config)#int s1/0
R4(config-if)#encapsulation frame-relay
R4(config-if)#frame-relay interface-dlci 405 ppp virtual-Template 1

are you doing any multilink
is you serial link up and reachable
First ensure that the link is up and reachable and then configure the EiGRP
if you are configuring an Multilink over Frame relay then please use the sample configs, and then configure the Eigrp or OSPF
if yes then plz first configure the
interface Multilink1
ip address A.B.C.D 255.255.255.
ppp multilink
ppp multilink group 1
and Add the multilink to the interface Virtual-templet 1
interface Virtual-Template 1
bandwidth 1536
no ip address
ppp multilink
ppp multilink group 1
interface Serial0/1/0:0
no ip address
encapsulation frame-relay
frame-relay lmi-type ansi
!
interface Serial0/1/0:0.1 point-to-point
frame-relay interface-dlci 312 ppp Virtual-Template1

Hi,
I am not using Multilink. This is PPP over Frame Relay. The problem is,Eigrp neighbor is established, but Networks are not advertised on peer end. I have tried many times, but still N/W is not advertise. Please help.

Hello Rupesh,
you say that the EIGRP neighbors are formed but you don't see the routes:
have you checked this using
sh ip eigrp topology
because there is the possibility that better routes are learned through another path.
also if you can post
sh ip eigrp neigh note the Q count in an healthy network this number has to be zero.
if there are pending EIGRP updates not ack by the neighbor this number is not zero.
Also you may need to adjust the ip MTU.
There was another thread reporting problems of missing EIGRP routes.
After troubleshooting with debug commands the problem was that depending on the size of the subnets to be advertised the size of each route data structure varies TLV (for a padding field) and so varies the size of the EIGRP update packet that carries mutiple TLVs of routes
Hope to help

Hi Sir,
I am only facing the problem if i create Virtual Templete. I have made the same setting which you have recommanded. If I remove Virtual Tunnel,every things work on FR. Any Clue.....

Hello Rupesh,
when you use the virtual-template you are putting a ppp frame inside a FR frame.
the suggestion is
int virtual-template xx
ip mtu 1480
Hope to help

I tried with MTU 1480 and 1500. Result is same.
04-08-2009 01:29 AM
Hello Rupesh,
so it is not an MTU issue.
Now, to see if this can be an issue related to multicast
router eigrp xx
neighbor x.y.z.k
we try to use only unicast packets for EIGRP communication
Hope to help
Giuseppe

Hi, Good Idea to send the unicast,I haven't tried this. I would do it on tomorrow morning, and update you accordingly. Hope it should work.

Hi, I did it , but it is not working. The have some clue- Show Fram-relay Map command is not showing any mapping. I manually mapped too, but eigrp is not sending the updates. If we debug, then multicast packets are being send/receive on virtual templete. Please help.

Hi Champions. Please help me. I also tried to establish EIGRP Unicast (neibhor command), still Routes are not published on Virtual Templete on FR.
04-29-2009 09:03 PM
Hi, Should I use Static mapping too ??
R4(config-if)#frame-relay interface-dlci 405 ppp virtual-Template 1
R4(config-if)#frame-relay map ip 141.141.45.5 405 broadcast
