Subject: [vpp-dev] mgre interface get UNRESOLVED fib entry.
Hi:
I try to config a mgre interface fellow those steps, then i get an
UNRESOLVED fib entry, is it right? I think it should be unicast-ip4-chain?
any examples of mgre config? Thinks.
create memif socket id 1 filename /work/memif1
create interface memif socket-id 1 master
set interface state memif1/0 up
set interface ip addr memif1/0 1.1.1.2/24
set interface rx-mode memif1/0 interrupt
create gre tunnel src 1.1.1.2 instance 1 multipoint
set interface state gre1 up
set interface ip addr gre1 2.1.1.2/32
create teib gre1 peer 3.3.3.3 nh 1.1.1.1
3.3.3.3 is not in the same subnet as 2.1.1.2/32, so it’s not a valid neighbour,
hence the UNRESOLVED.
