Hi Vijay,
No, the ESP encrypt code does not account for the egress interface’s MTU. the
outer/encapped packet will be fragmented at the phy.
But for a route based VPN, where you are protecting a tunnel with an SA, then
the encrypt/encap happens after any fragmentation by the tunnel interface.

Hi Sastry,
There are lots of examples of MPLS routes and VRF creation in test/test_mpls.py
and BFD session creation in test/test_bfd.py.
Or if you’d prefer there’s src/plugins/unittest/fib_test.c with fib_test_bfd.

Hi Vijay,
It sounds like the SA you programme did not install. As you say, DES is
insecure, so we don’t even test it anymore. I would suggest you start with a UT

For L3 forwarding you can use the per-adjacency counters. This are not enabled
by default, because, like all stats, they come with a performance cost.
