That multicast address (224.0.0.10) is for EIGRP, OSPF is on
224.0.0.5/.6
Also, why do have a frame map statement under each interface for that
interface??? Excerpt follows....
interface Serial0
ip address 170.10.235.2 255.255.255.240
.
.
frame-relay map ip 170.10.235.2 102 broadcast

All routers can ping one another.
It appears that the multicast on r2 is broken somehow. Here is the
output of
'deb ip pack' on r2:
00:28:33: IP: s=170.10.242.2 (local), d=224.0.0.10 (Loopback0), len 60,
sending
broad/multicast
00:28:33: IP: s=170.10.242.2 (Loopback0), d=224.0.0.10, len 60, rcvd 2
r2(config-if)#
00:28:35: IP: s=170.10.20.2 (local), d=224.0.0.10 (Ethernet0), len 60,
sending b
road/multicast
*Notice that it is not sending any multicast hellos to out of
170.10.235.2
(its serial interface to connect to r5).
Just in case you're thinking what I'm thinking, here is the ospf configs
on
r2:
!
router ospf 1
network 170.10.23.0 0.0.0.255 area 0
network 170.10.235.0 0.0.0.15 area 0
So, yes; it is in the ospf process, and yes, the interface is dlso
up/up:
r2#sh ip int brie
Interface IP-Address OK? Method Status
Prot
ocol
Ethernet0 170.10.20.2 YES NVRAM up
up
Loopback0 170.10.242.2 YES NVRAM up
up
Serial0 170.10.235.2 YES NVRAM up
up
So, why is it NOT showing up on the database?
r2#sh ip ospf data
OSPF Router with ID (170.10.242.2) (Process ID 1)
Router Link States (Area 0)
Link ID ADV Router Age Seq# Checksum Link
count
170.10.242.2 170.10.242.2 357 0x80000003 0x96A4 1
All it is showing is just the loopback/RID type 1 lsa. Any ideas?
Thanks,
Daniel

Scenario: OSPF over multipoint frame-relay; r5 as hub, r2 and r3 as
spokes.
r5 and r3 form adjacencies, but r2 and r5 do not. It appears that r5 is
not
receiving hellos from r2, although r2 receives them from r5.

frame-relay map ip 170.10.235.3 402 broadcast
frame-relay map ip 170.10.235.5 402 broadcast
end
Normally, stuck-in-INIT states are caused by leaving out the 'broadcast'
parameter, but this is not the case. Further, if it was a
misconfiguration
issue, r3 would also exhibit the same symptoms. IOS bug perhaps?

Daniel
