Operational problem: active bridge between MAE-WEST and PAIX

  • From: Dave Rand

While trying to track down a strange and unusual problem tonight, I
discovered that someone is running a switch or a bridge between mae-west and
the Palo Alto Internet Exchange.

After adding an ip address 198.32.176.222 255.255.255.0 sec to my
mae-west router, I was able to:

mae-west#ping 198.32.176.252

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 198.32.176.252, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/109/524 ms
mae-west#sh ip arp 198.32.176.252
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  198.32.176.252          0   0800.2bb6.b8f7  SNAP   Fddi4/1/0
mae-west#

If you are trying to track down unusual problems between mae-west
and PAIX, you might want to check this out.

Of course, IMHO, the bridge should be taken down or severly filtered.
On the other hand - it does mean that everyone only at mae-west
should immediately apply for PAIX IP addresses :-)
