Cisco IOS, IOS-XR, and Junos VPLS Interoperability config (signaling only)

This post is the second part of two series posting about MPLS L2 service interoperability between Cisco IOS, Cisco XR and Junos. This post will cover LDP-based VPLS configuration. The purpose of this post is mainly for my personal notes.

Disclaimer: Only signaling part will be verified, no CE to CE traffic test has been performed due to CE unavailability.

I will start with all the configuration first, the verification command and its result will follow.

Notes:

• The VPLS is using circuit id 107 and consist of 3 routers: 7606, CRS1, and M120.
• Junos and IOS-XR seem compatible each other, but there is a strange verification result on IOS.
• On Junos (M120), the circuit towards 7606 and CRS1 are marked as UP. 
• Similar as Junos, on XR (CRS1), the circuit towards M120 and 7606 are marked as up
• But, on the 7606, the circuit towards M120 and CRS1 are marked as Down
• Currently i have no idea to make the circuit on 7606 side UP. I also can't find any command with more information that can explains why the circuits are down.
• The software version of each router is:
• 7606: c7600s72033-adventerprisek9-mz.122-33.SRE4
• CRS1: Cisco IOS XR Software, Version 4.0.1[Default]
• M120: Junos 10.4R4.5

Note:

• VC 100 is l2 circuit betwen IOS (7606) and IOS-XR (CRS1)
• VC 104 is l2 circuit betwen IOS (7606) and JUNOS (M120)
• VC 106 is l2 circuit betwen JUNOS (M120) and IOS-XR (CRS1)
• Juniper has command to ignore mtu mismatch and encapsulation mismatch, but seems it affects the Juniper side only. For example, if the MTU is different between XR and Juniper, the ignore-mtu-mismatch command will bring the l2circuit up on juniper side but on the XR side, it still complaining about the MTU mismatch. So far, i can't find any command to ignore mtu mismatch on neither Cisco IOS or IOS-XR
• The software version of each router is:
• 7606: c7600s72033-adventerprisek9-mz.122-33.SRE4
• CRS1: Cisco IOS XR Software, Version 4.0.1[Default]
• M120: Junos 10.4R4.5

BGP for VPLS (Part 2)

This time, I'' try to provide some quick updates on the my previous post http://rendoaw.blogspot.com/2011/09/bgp-for-vpls.html

In my previous post, i mentioned that Cisco IOS-XR introduced "BGP Auto Discovery With BGP Signaling" feature on ASR9k (3.9.1) and CRS-1 (IOS-XR 4.0.1), and last week, i have chance to test it on real Juniper and IOS-XR router with some limitations:
- no CE is connected to the PE
- the routers are in remote location, tcpdump/sniffing the traffic was not possible.

What i was trying to achieve is simply to get the BGP-signaled VPLS up in term of control plane perspective, and what i have achieved so far are:

• The autodiscovery feature is works on both Juniper and CRS, Juniper router can find the CRS1 and its VPLS instance, and also the other way around.
• From Juniper side, the circuit is up but from CRS1 the circuit is down because of the MTU mismatch. 
• Juniper doesn't allow "mtu" command inside VPLS-BGP routing-instance to manually adjust the MTU, and Juniper also doesn't allow "ignore-mtu-mismatch" command.
• I created two VPLS instances betwen 2 PE, one is using LDP signal and the second one is using BGP. For both VPLS, the same physical interface is used, and i use two different sub-interface to separate those two VPLS instances.
• The LDP based VPLS between CRS and Juniper is up and running [see blue color below], but the BGP-VPLS got MTU mismatch on CRS side [see red color below]
• I suspect that Cisco expects MTU information from remote attached circuit (AC) to be advertised from BGP but Juniper seems doesn't care about the MTU for BGP signaled VPLS.
• Previously it is known that Juniper is using FEC128 and Cisco is using FEC129 refer to http://forums.juniper.net/t5/Routing/Cisco-and-Juniper-VPLS-Integration-using-BGP/td-p/42308,but from the error log [5] below, seems Juniper is already using FEC129 for auto discovery
• I tried to use vpn-id in "l2vpn-id:AS:VCID" format, to force Juniper to use FEC128 but seems Cisco has different format for vc-id. Cisco format is vpn-id VCID, without AS. And the result, both CRS and Juniper can not find each other.

As the conclusion, i failed to make BGP signaled VPLS works between Junos and IOS-XR, it is either because of I don't know the knob and the trick, or there is an MTU issue that need to be fixed by those  2 vendors. 


I am open for any suggestion but not sure if i can test it again soon due to the hardware availability.

Here are some config and result of my experiment:
note: VCID 706 and VlanID 801 are LDP based VPLS, vlan 778 and VCID 778 are BGP-based VPLS.
