MVPN interoperability -- Cisco and Juniper

‎05-18-2017 03:17 PM

Hello,

I need help with connecting Cisco and Juniper PE's for MVPN.

 

Currently in my lab, I have full L3VPN connectivity between all of the CE's  (behind Juniper and Cisco PE's).  No problem.

 

Also, I have full MVPN connectivity between the sister PE's for Cisco and separately between the Juniper PE's.   No problems setting up Cisco-to-Cisco connectivity or Junos-to-Junos PE connectivity.

*ISIS

*LDP/MPLS

*L3VPN BGP

 

Now I need to connect the different vendor configurations. Cisco-to-Juniper.

 

Easy way to do this?   I cannot be the first one to go through this.

Mark

P.S.  This is not Draft-Rosen.    It is NG-MVPN.   Again, I have no issues between Juniper devices. Just need to connect them through mpls to the Cisco setup.

Hi

Not an easy topic

therefore my answer: It DEPENDS

 

MVPN there are around 20 different possibilities for setup

 

signalling (BGP or LDP), autodiscovery (yes/no) core tree protocol (PIM,RSVP,LDP), I-PMSI or s-PMSI., receiver-site-only,.....

 

so if setup parameters are equal then yes change the RT and let them interop, if setup is different you could do an INTER-AS-approach , connecting one net to the other via "external connections" ( outside the MPLS/VPN domain) and connecting the RPs via MSDP.

You will not easily find an expert on MVPN who knows Cisco AND Juniper but there is at least one Smiley Happy

 

regards

Alexander

Have you seen this sample configuration for the Junos side?

 

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/mcast-mbgp-extranets.html

 

The protocols are reasonably standard so if the Cisco nodes also support MVPN and the signaling protocols I don't see why it would not work.
