The exchange *seems* fine, but I can't reliably ping the route servers right now. My BGP sessions to them are up and stable, but ICMP isn't operating "normally" - has anything changed? This started at 15:24 CDT today: [stahr@ctg-bastion ~]$ ping -c 10 206.108.255.1 PING 206.108.255.1 (206.108.255.1) 56(84) bytes of data. 64 bytes from 206.108.255.1: icmp_seq=7 ttl=59 time=7.06 ms --- 206.108.255.1 ping statistics --- 10 packets transmitted, 1 received, 90% packet loss, time 9000ms rtt min/avg/max/mdev = 7.062/7.062/7.062/0.000 ms [stahr@ctg-bastion ~]$ ping -c 10 206.108.255.2 PING 206.108.255.2 (206.108.255.2) 56(84) bytes of data. 64 bytes from 206.108.255.2: icmp_seq=2 ttl=59 time=7.13 ms 64 bytes from 206.108.255.2: icmp_seq=6 ttl=59 time=6.98 ms 64 bytes from 206.108.255.2: icmp_seq=7 ttl=59 time=6.94 ms 64 bytes from 206.108.255.2: icmp_seq=10 ttl=59 time=7.05 ms --- 206.108.255.2 ping statistics --- 10 packets transmitted, 4 received, 60% packet loss, time 9001ms rtt min/avg/max/mdev = 6.942/7.028/7.135/0.093 ms [stahr@ctg-bastion ~]$ ping -c 10 206.108.255.52 PING 206.108.255.52 (206.108.255.52) 56(84) bytes of data. 64 bytes from 206.108.255.52: icmp_seq=1 ttl=61 time=14.0 ms 64 bytes from 206.108.255.52: icmp_seq=2 ttl=61 time=14.5 ms 64 bytes from 206.108.255.52: icmp_seq=3 ttl=61 time=14.0 ms 64 bytes from 206.108.255.52: icmp_seq=4 ttl=61 time=13.6 ms 64 bytes from 206.108.255.52: icmp_seq=5 ttl=61 time=13.0 ms 64 bytes from 206.108.255.52: icmp_seq=6 ttl=61 time=12.7 ms 64 bytes from 206.108.255.52: icmp_seq=7 ttl=61 time=12.2 ms 64 bytes from 206.108.255.52: icmp_seq=8 ttl=61 time=11.7 ms 64 bytes from 206.108.255.52: icmp_seq=9 ttl=61 time=11.2 ms 64 bytes from 206.108.255.52: icmp_seq=10 ttl=61 time=11.9 ms --- 206.108.255.52 ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 9002ms rtt min/avg/max/mdev = 11.289/12.913/14.502/1.052 ms [stahr@ctg-bastion ~]$ Any new policing policy applied today?
