Hi, We are testing SR Proxy in VPP. Topology we are using is something like this : -
Host 3 (implementing SR Proxy) directly connected to Host 4 (SR Unaware) via two interfaces GigabitEthernet0/9/0 (acting as OIF) and GigabitEthernet0/a/0 (acting as IIF). Issue 1 : We can’t see decapsulated packet going to Host 4 via GigabitEthernet0/9/0 when next hop is an IPv6 address (using encap mode) When we configured a End.AD segment using the command : sr localsid address 2001:db8:1:c5:1:: behavior end.ad<http://end.ad> nh 2001:5b0:4321::121 oif GigabitEthernet0/9/0 iif GigabitEthernet0/a/0 where 2001:5b0:4321::121 is the interface IPv6 IP of Host 4 which is directly connected to Host 3’s GigabitEthernet0/9/0. Here, we don’t see any decapsulated IPv4 packet going to Host 4 via GigabitEthernet0/9/0. Whereas, if we execute the command : sr localsid address 2001:db8:1:c5:1:: behavior end.ad<http://end.ad> nh 112.112.112.162oif GigabitEthernet0/9/0 iif GigabitEthernet0/a/0 where 112.112.112.162<http://112.112.112.162> is the interface IPv4 IP of Host 4 which is directly connected to Host 3’s GigabitEthernet0/9/0. Here, decapsulated IPv4 packet is reaching Host 4 and everything works fine. Issue 2 : When using inline mode we always get bad traffic for End.ADimplementation When we configure a End.AD segment using the command : sr localsid address 2001:db8:1:c5:1:: behavior end.ad<http://end.ad> nh 2001:5b0:4321::121 oif GigabitEthernet0/9/0 iif GigabitEthernet0/a/0 where 2001:5b0:4321::121 is the interface IP of Host 4 which is directly connected to Host 3’s GigabitEthernet0/9/0. When we execute the command : show sr localsids We get the following output : SRv6 - My LocalSID Table: ========================= Address: 2001:db8:1:c5:1:: Behavior: End.AD (Endpoint with dynamic proxy to SR-unaware appliance) Next-hop: 2001:5b0:4321::121 Outgoing iface: GigabitEthernet0/9/0 Incoming iface: GigabitEthernet0/a/0 Good rewrite traffic: [0 packets : 0 bytes] Bad rewrite traffic: [2291 packets : 166136 bytes] Good traffic: [0 packets : 0 bytes] Bad traffic: [775 packets : 136400 bytes] -------------------- Are we missing out anything in the configuration part for the above issues?
