Hi Shoaib, Have you tried enabling "mls mpls tunnel-recir" in your 7600?
Best Regards Ted -----Original Message----- From: cisco-nsp [mailto:[email protected]] On Behalf Of Shoaib Farhan Sent: den 12 december 2016 04:36 To: [email protected] Subject: [c-nsp] SITE-2-SITE GRE Tunnel Problem with 7600 in Core Network Hi, We are having a strange issue after deploying 7604 Router in our Network. When we connect our customer to 7604 Router theirGRE tunnel never got up. But if we use 7200 router then it is working fine. Here is topology diagram: *CE1==>PE1-SWITCH==>PE1-ROUTER===MPLS CORE NETWORK=====PE2-ROUTER===>PE2-SWITCH====>CE2* Problem is at PE1-ROUTER where 7604 is in use. Tunnel showing UP/Down at CE1 and UP/UP at CE2. sh module Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 1 5 Route Switch Processor 720 10GE (Activ RSP720-3CXL-10GE JAE144907ZS 2 11 7600 ES+ 76-ES+XC-20G3CXL JAE1342LP0L Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ----- ------------- ------------ ------- 1 68ef.bdd3.5e20 to 68ef.bdd3.5e27 1.0 12.2(33r)SRD 15.3(3)S Ok 2 0024.f94f.1530 to 0024.f94f.154f 1.3 12.2(33r)SRE 15.3(3)S Ok Mod Sub-Module Model Serial Hw Status ---- --------------------------- ------------------ ----------- ------- ------- 1 Policy Feature Card 3 7600-PFC3CXL-10GE JAE144906SY 1.2 Ok 1 C7600 MSFC4 Daughterboard 7600-MSFC4 JAE14450XVI 2.2 Ok 2 7600 ES+ DFC XL 7600-ES+3CXL JAE131885KB 1.1 Ok 2 ES+ 1xTGE XFP 10xGE SFP 7600-ES+20C JAE1343LYS4 1.0 Ok Mod Online Diag Status ---- ------------------- 1 Pass 2 Pass sh version Cisco IOS Software, c7600rsp72043_rp Software (c7600rsp72043_rp-ADVIPSERVICESK9-M), Version 15.3(3)S6, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2015 by Cisco Systems, Inc.
