Hi Jingrong

RFC 6425 updates 4379 as such it uses the same port, this is my understanding.

So yes we are proposing the same port as LSP ping
lsp-ping           3503        udp    MPLS LSP-echo Port

I think this is sufficient enough as the new sub-tlvs will identify the packet accordingly.

Thanks
Hooman

Subject: [pim] Question about SR P2MP Policy Ping

Hi,
Following up the comment in IETF111 PIM WG online, my question is this.
Ping procedure needs some kind of encapsulation of Echo Request and Echo Reply as in RFC4379, first an UDP encapsulation, and then an IP encapsulation, and lastly the tunnel header encapsulation of MPLS/P2MP and I guess the same for SR-P2MP-policy.
The UDP encapsulation need an UDP port, and the IP encapsulation need src/dst IP or IPv6 addresses.
Are these UDP/src/dst the same as RFC4379 or have some different ones ?

Thanks
Jingrong
