When vpp configured MPLS the ping packet from CE to CE is failed ,the assertion occured at the meantime.The assertion is shown below： /home/vpp/build-data/../src/vnet/ip/ip4_forward.c:2635 (ip4_rewrite_inline) assertion `ip0->checksum == ip4_header_checksum (ip0)' fails Aborted /home/vpp/build-data/../src/vnet/ip/ip4_forward.c:2497 (ip4_rewrite_inline) assertion `ip1->checksum == ip4_header_checksum (ip1)' fails Aborted Thanks, xyxue From: Neale Ranns (nranns) Date: 2017-05-27 18:25 To: 薛欣颖; vpp-dev Subject: Re: [vpp-dev] MPLS L3VPN PING FAILED Hi Xyxue, One issue at a time please J let’s start with getting L3VPN to work correctly. Please describe what the 3 flows are that we you discussing; - Fade flow - Ip4 flow - Mpls flow Describe, as in what headers they have, addressing etc. The IP chksum will change from CE->CE since the IP TTL decrements. /neale
