[j-nsp] LSP's with IPV6 on Juniper

[craig washington]

Yea, I figured I would need to do something along those lines.

Our CORE is currently dual stacked and running OSPF for v4 and v6 with prefixes being advertised so that was a little bit more work than desired.

So my fix was leaving everything as is and just changing the next-hop from self to the IPv4 address of the advertising PE under the v6 group which is basically what would be happening anyway if I deleted the groups and added everything to the v4 group.


My overall goal was to try to get IPv6 prefixes to use the same LSP's as their IPv4 counterparts with as little trouble as possible. (not adding new protocols or changing existing protocols if possible)

Simplest way I found was just changing the next hop. Everything worked as expected when that was done.


I just didn't know if there was anything else anyone else was doing of if anyone came across a similar situation.

I now know about LDPv6, which will be looked into and I still have some research to do on SPRING.

For 6PE you have to:
- delete the iBGP ipv6 groups
- add family ipv6 labeled-unicast explicit-null to the IPv4 iBGP groups
- add ipv6-tunneling to protocol mpls.
- make sure your IGP is not advertising IPv6 addresses

This is the way it's configured, with either RSVP-TE or LDP.
