The MPLS-OPS Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] Frame based MPLS between UNISPHERE ERX and CISCO 7507
I would like your help on the following:
GKP---ERX---7500---3660
MPLS is active between 7507 & ERX.
pe-7507#sh mpls ldp discovery
Local LDP Identifier:
10.0.1.252:0
Discovery Sources:
Interfaces:
ATM4/0/0.1 (ldp): xmit/recv
LDP Id: 10.0.1.253:0
ATM4/0/0.2 (ldp): xmit/recv
LDP Id: 10.0.1.254:0
We are interested in atm4/0/0.2.
Also :

pe-7507#sh mpls interfaces

Serial4/1/4:0 Yes No No
Serial4/1/7:0 Yes No No
ATM4/0/0.1 Yes (ldp) No Yes
ATM4/0/0.2 Yes (ldp) No Yes
And to ERX side:
RND_ERX1:LAB-BB#sh mpls interface
Interface atm9/3.3 Up
RSVP not configured
LDP enabled with profile default, CR-LDP disabled
IP interfaces on this MPLS interface:
10.0.1.21/30
MPLS Statistics:
Rcvd: 0 failed lbl lookup, 0 octets, 0 hcOctets
0 pkts, 0 hcPkts, 0 errors, 0 discards
Sent: 0 octets, 0 hcOctets, 0 pkts
0 hcPkts, 0 errors, 0 discards
Interface atm9/3.1 Up
RSVP not configured
LDP enabled with profile default, CR-LDP disabled
IP interfaces on this MPLS interface:
10.0.1.1/30
Session to 10.0.1.253 is operational (active)
Session negotiated LDP advertisement mode is Downstream Unsolicited
MPLS Statistics:
Rcvd: 0 failed lbl lookup, 4638 octets, 0 hcOctets
87 pkts, 0 hcPkts, 0 errors, 0 discards
Sent: 0 octets, 0 hcOctets, 0 pkts
0 hcPkts, 0 errors, 0 discards
Interface atm9/3.2 Up
RSVP not configured
LDP enabled with profile default, CR-LDP disabled
IP interfaces on this MPLS interface:
10.0.1.5/30
Session to 10.0.1.252 is operational (active)
Session negotiated LDP advertisement mode is Downstream Unsolicited
MPLS Statistics:
Rcvd: 0 failed lbl lookup, 120708 octets, 0 hcOctets
669 pkts, 0 hcPkts, 0 errors, 0 discards
Sent: 0 octets, 0 hcOctets, 0 pkts
0 hcPkts, 0 errors, 0 discards
We are interested in atm9/3.2 interface.
The network between GKP-ERX is 10.0.1.24 /30. From the 3660 and when MPLS is
active i can not do a ping to 10.0.1.25 (which is serial interface of the
ERX). By disabling MPLS everything works fine.
As far as label exchange is concerned :
pe-7507#sh mpls forwarding-table 10.0.1.24
Local Outgoing Prefix Bytes tag Outgoing Next Hop
tag tag or VC or Tunnel Id switched interface
23 29 10.0.1.24/30 0 AT4/0/0.2 point2point
pe-7507#sh mpls forwarding-table 10.0.1.25
Local Outgoing Prefix Bytes tag Outgoing Next Hop
tag tag or VC or Tunnel Id switched interface
23 29 10.0.1.24/30 0 AT4/0/0.2 point2point
ERX LABELS:
RND_ERX1:LAB-BB#sh mpls forwarding destination 10.0.1.24 255.255.255.252
LSP tail-0a000118-30-22949 for 10.0.1.24/255.255.255.252
In label 29 on atm9/3.1
0 pkts, 0 hcPkts, 0 octets
0 hcOctets, 0 errors, 0 discardPkts
LSP tail-0a000118-30-22954 for 10.0.1.24/255.255.255.252
In label 29 on atm9/3.2
296 pkts, 0 hcPkts, 58268 octets
0 hcOctets, 0 errors, 0 discardPkts
We are interested in the second entry which is the link to 7500.
But:
RND_ERX1:LAB-BB#sh mpls forwarding destination 10.0.1.25 255.255.255.255
RND_ERX1:LAB-BB#
I believe that it has something to do with the ERX configuration.
The ERX conf is as follows:

ERX has the folowing commands and the documentation is not very clear on
them:
RND_ERX1:LAB-BB(config)#mpls topology-driven-lsp ?
ip-interfaces Enable the creation of IP interfaces over LSPs
ip-profile Configure the profile for IP interfaces on top of the
topology-driven LSP
<cr>
RND_ERX1:LAB-BB(config)#mpls topology-driven-lsp ip-
RND_ERX1:LAB-BB(config)#mpls topology-driven-lsp ip-i
RND_ERX1:LAB-BB(config)#mpls topology-driven-lsp ip-interfaces ?
access-list Configure an access-list for the LSP prefixes
egress Create IP interfaces over egress LSPs only
host-only Create IP interfaces only over LSPs to host addresses
ingress Create IP interfaces over ingress LSPs only
prefix-list Configure an prefix-list for the LSP prefixes
<cr>
I wonder if somebody could help me.
Thanks in advance,
Panos.
