Hi vpp gtpu experts,
We have requirement where
- we create gtpu tunnel
- Now, we will hit gtpu input, where we will receive gtpu packet and
when we send it out on the interface replace the tied with tried and
massage the ip address of src and destination and send the packet out
vpp# show vlib graph gtpu4-input
Name Next Previous
gtpu4-input error-drop [0] ip4-gtpu-bypass
l2-input [1] ip4-udp-lookup
ip4-input [2]
ip6-input [3]
vpp#
vpp# show vlib graph gtpu4-encap
Name Next Previous
gtpu4-encap error-drop [0] ip4-dvr-dpo
ip4-lookup [1] ip4-arp
ip6-lookup [2] ip4-midchain
ip4-load-balance [3] ip4-mcast-midchain
ip4-rewrite-mcast
ip4-rewrite-bcast
ip4-rewrite
interface-output
vpp# show vlib graph gtpu4-input
Name Next Previous
gtpu4-input error-drop [0] ip4-gtpu-bypass
l2-input [1] ip4-udp-lookup
gtpu4-encap [2]
gtpu6-encap [3]
Now we want next gtpu-input to be gtpu4-encap and the next of that to
ip4-load-balance or directly send it out. Is such thing possible.
Thanks,
Regards,
Venu
