Issue with RIPng over Frame Relay NBMA posted 10/11/2007
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


Hi Group,

I'm facing an issue running RIPng over frame relay NBMA. Any help is
welcome. My config as follows:

R6
--
ipv6 unicast-routing
!
interface Serial0/0/0
 no ip address
 encapsulation frame-relay
 ipv6 address 2001:1:1:26::6/64
 ipv6 rip big enable
 frame-relay map ipv6 2001:1:1:26::2 601 broadcast
 no frame-relay inverse-arp
!
ipv6 router rip big

R2
--
interface Loopback1
 no ip address
 ipv6 address 2000:1:2:2::2/64
 ipv6 rip big enable
!
interface Serial0/0/0
 no ip address
 encapsulation frame-relay
 ipv6 address 2001:1:1:26::2/64
 ipv6 rip big enable
 frame-relay map ipv6 2001:1:1:26::6 106 broadcast
!
ipv6 router rip big

Verification:
-------------
R2#sh ipv int s 0/0/0
Serial0/0/0 is up, line protocol is up
  IPv6 is enabled, link-local address is FE80::21B:54FF:FECE:2072
  Global unicast address(es):
    2001:1:1:26::2, subnet is 2001:1:1:26::/64

R6#pi FE80::21B:54FF:FECE:2072
Output Interface: serial0/0/0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FE80::21B:54FF:FECE:2072, timeout is 2
seconds:

     via FE80::21B:54FF:FECE:2072, Serial0/0/0

(1) I'm not able to ping to R2's link-local address from R6 but can ping its
global unicast address.
(2) R6 learns R2's loopback1 subnet address via RIP but can't ping R2's
loopback1 address.
(3) I notice the next-hop address of the RIP route is R2's link-local
address. I guess the reason why R6 can't ping R2's loopback1 has to do with
the issue of not being able to ping R2's link-local address.
(4) I have no issue if I re-configured the frame relay to p2p subinterfaces.

Did I miss anything in my config? Reloading both routers doesn't help.
Please advise.


Thank you.
