[rbak-nsp] IPv6 BGP - inter-context

Hi Sebastian,

True.

You can't do intercontext routing with IPv6. This is a limitation in SEOS software.

You have to take a loop (crossover) cable and connect two ports of your machine together.
Then configure a IPv6 transfer network on it. 

Example config:

##############################################
context local
 interface loopcable
  description IPv6 routing to context xyz
  ipv6 address xxxx:xxxx:xxxx::1/64

context xyz
 interface loopcable
  description IPv6 routing to context local
  ipv6 address xxxx:xxxx:xxxx::2/64

port ethernet 4/10 
 description LoopCable to 5/10
 bind interface loopcable local

port ethernet 5/10 
 description LoopCable to 4/10
 bind interface loopcable xyz
##############################################

So you have to split your traffic this way:

- IPv4 goes via intercontext routing
- IPv6 goes via the loop cable

Think of the limited bandwidth (by hardware) on your loop cable if you see any IPv6 bandwidth problems in the future! =;-)
