Toloupe,
1st I have to say that I couldn't find this task in IE Vol2 work book. (Lab
5 , task 4.4 is related to BGP).
I have some similar problems before.
Seems you don't have access to routes to Virtual-Access2. Can you ping
192.168.1.1 from R5? Do you have basic reachability?
Try to create Virtual-template 2, and attach it to DLCI 502. With IP
unnumbered virtual-template 1.
Reza

Subject: OSPF over PPPoFR
Hi All
I couldnt solve IE Core lab 5 task 4.4 so i decided to run the PPPoFR
alone in a separate test lab.
I still have the same results.
Scenario: R5 is the hub of the FR circuit with connections on dlci's
501 and 502 to R1 and R2 respectively. they all run OSPF on the common
192.168.1.0 subnet.
R1 has loopback 0 (1.1.1.1) in area 0 and R2 has loopback 0 (2.2.2.2)
in area 125
Problem. R5 installs the same virtual-access as the exit interface for
the ospf routes learned regardless of the advertising router.
Configuration and show output below.

R5#ping 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/34/68 ms
R5#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
IMO, R5 cant reach R1's loopback because it is using Virtual-Access2
(which is cloned to R2's loopback)
All opinions are HIGHLY welcome.
Thanks..
