Hi folks,
After reading some docs about configuration options between them I have not connectivity yet.
My topology is as follow:
CEside <> JuniperM20 <> JuniperM20 <> Cisco7606 <> CEside
The configs:
neighbor y.y.y.y {
interface ge-2/0/0.1950 {
virtual-circuit-id 1950;
no-control-word;
mtu 1500;
ignore-encapsulation-mismatch;
ignore-mtu-mismatch;
}
show configuration interfaces ge-2/0/0.1950
encapsulation vlan-ccc;
vlan-id 1950;
family ccc;
sh run int g1/14.1950
interface GigabitEthernet1/14.1950
description PW-TEST-ING
encapsulation dot1Q 1950
xconnect x.x.x.x 1950 encapsulation mpls
end
Some troubleshooting commands:

Any ideas would be appreciated.

Hi Diego,
Do you have an functionning LSP from the Cisco to the Juniper? Can you do a "show ip cef x.x.x.x int" from the Cisco side.
Regards
Hi Harold,
There is the output of "show ip cef x.x.x.x int" command from the Cisco rtr.

Hi Diego,
What IOS version do you run on the 7606?
Regards
Hi Harold,
Sorry for the delay, the IOS version that we're running on the C7606 is:
#sh ver | i IOS
Cisco IOS Software, c7600s3223_rp Software (c7600s3223_rp-ADVIPSERVICESK9-M), Version 12.2(33)SRB7, RELEASE SOFTWARE (fc1)
Thx,

Hi Diego,
This is a pretty old version of IOS. I would recommend you upgrade to something more recent before proceeding with more troubleshooting.
Regards
Hi Harold,
Which version of IOS do you recommend to upgrade based on the following features of the box?
cisco CISCO7606-S (R7000) processor (revision 1.1) with 983040K/65536K bytes of memory.
Processor board ID FOX1340GJxx
R7000 CPU at 300Mhz, Implementation 0x27, Rev 3.3, 256KB L2, 1024KB L3 Cache
Last reset from power-on
35 Virtual Ethernet interfaces
146 Gigabit Ethernet interfaces
1915K bytes of non-volatile configuration memory.
65536K bytes of Flash internal SIMM (Sector size 512K).
Configuration register is 0x2102
Thx,
-d
Hi Diego,
I would recommend the latest version (15.3(1)S2). You currently do not have enough flash memory and will therefore need to upgarde.
Regards
Thx Harold, we'll be upgrading to the latest version and keep you posted.
