Hi guys/girls
I am having a lot of problems making NLSP form up over frame relay point =
to point sub interfaces. Everything else is fine, PPP, ATM, HDLC, Token =
Ring and Ethernet all work fine!
Basically sometimes it works, and others it doesnt.
I have done lots of debugs, and it appears that 1 router is receiving =
Hellos but not sending any back
The link is configured with IPXWAN, and sometimes removing the IPXWAN =
config and replacing it again lets the neighbors come up. I presumed =
this was because IPXWAN would retry and time out before my DLCI got =
bound to the interface
The layout is simple
R2-----dlci40----FR.Switch-----dlci40-----R6
The configs are simple, R2 is in 2 NLSP areas (100 and 200) and R6 is =
just in area 200
ROUTER 6
interface Serial1
description FRAME CONN TO R2
no ip address
encapsulation frame-relay
!
interface Serial1.1 point-to-point
ip address 213.38.32.249 255.255.255.128
ipx ipxwan 0 unnumbered Router6
ipx nlsp enable
ipx nlsp rip off
ipx nlsp sap off
frame-relay interface-dlci 40 =20
ipx router nlsp
area-address 200 FFFFFF00
The NLSP adj debug looks like it is sending hellos over int s1.1, but =
not receiving any over s1.1
NLSP-Adj: Sending serial IIH on Serial1.1
NLSP-Adj: Sending serial IIH on Serial1.1

As you can see, the Hellos are received from R6 but R2 is not sending =
any back - does anyone know why this is?
The frame is point-to-point sub ints, so there is no Layer2 mapping =
problem, both routers are in the same NLSP area, and I have had it =
working before - do the IPX internal nets have to be inside the NLSP 200 =
process area aswell - do they have to match?
00:38:27: NLSP-Adj: Rec L1 IIH from 0000.0c59.f651 (Ethernet0), cir type =
L1, cir id 0000.0C59.F651.03 (no-mc)
00:38:30: NLSP-Adj: Rec serial IIH from DLCI 40 (Serial0.1), cir type =
L1, cir id 03
00:38:30: NLSP-Adj: old state INIT, new state INIT
00:38:36: NLSP-Adj: Rec L1 IIH from 0000.0c59.f651 (Ethernet0), cir type =
L1, cir id 0000.0C59.F651.03 (no-mc)
00:38:40: NLSP-Adj: Rec serial IIH from DLCI 40 (Serial0.1), cir type =
L1, cir id 03
00:38:40: NLSP-Adj: old state INIT, new state INIT
00:38:41: NLSP-Adj: Sending L1 IIH on Ethernet0
Ethernet 0 connects to another NLSP peer in area 100
Any help at all appreciated
Cheers
Simon
