Hi, Would anyone have any idea why IP packets with options are forwarded via MX104 20x faster then regular IP packets ?
"fast" PFE path - 24-35 ms "slow" RE path - 1-4 ms Example (I used record route to force IP Options punt to slow path): rraszuk@cto-lon2:~$ ping 62.189.71.209 -R -v PING 62.189.71.209 (62.189.71.209) 56(124) bytes of data. 64 bytes from 62.189.71.209: icmp_seq=1 ttl=63 time=1.44 ms RR: 69.191.176.206 10.249.23.7 62.189.71.209 10.249.23.7 69.191.176.206 64 bytes from 62.189.71.209: icmp_seq=2 ttl=63 time=1.38 ms 64 bytes from 62.189.71.209: icmp_seq=3 ttl=63 time=1.46 ms 64 bytes from 62.189.71.209: icmp_seq=4 ttl=63 time=1.41 ms 64 bytes from 62.189.71.209: icmp_seq=5 ttl=63 time=1.49 ms 64 bytes from 62.189.71.209: icmp_seq=6 ttl=63 time=1.46 ms 64 bytes from 62.189.71.209: icmp_seq=8 ttl=63 time=1.52 ms 64 bytes from 62.189.71.209: icmp_seq=9 ttl=63 time=2.84 ms 64 bytes from 62.189.71.209: icmp_seq=10 ttl=63 time=1.77 ms ^C --- 62.189.71.209 ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 9014ms rtt min/avg/max/mdev = 1.386/1.892/4.117/0.849 ms Now I use normal ping running between 62.189.71.209 & 69.191.176.206 in "fast" path: rraszuk@cto-lon2:~$ ping 62.189.71.209 -v PING 62.189.71.209 (62.189.71.209) 56(84) bytes of data. 64 bytes from 62.189.71.209: icmp_seq=1 ttl=63 time=24.1 ms 64 bytes from 62.189.71.209: icmp_seq=2 ttl=63 time=31.5 ms 64 bytes from 62.189.71.209: icmp_seq=3 ttl=63 time=24.1 ms 64 bytes from 62.189.71.209: icmp_seq=4 ttl=63 time=24.1 ms 64 bytes from 62.189.71.209: icmp_seq=5 ttl=63 time=24.0 ms 64 bytes from 62.189.71.209: icmp_seq=6 ttl=63 time=24.1 ms ^C --- 62.189.71.209 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5006ms rtt min/avg/max/mdev = 24.097/25.369/31.563/2.774 ms rraszuk@cto-lon2:~$ Best, R. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
