- I have a router in San Francisco with two token ring interfaces,
- 182.9.200.249 255.255.0.0 and 158.67.145.126 255.255.255.128.
-
- When I ping a router in New York with a primary ethernet interface of 192.9.200.220,
- 255.255.255.0, the ping times out.
- A trace reveals that by changing the source address, the ping succeeds.
-
- The secondary address 147.23.23.2 255.255.0.0 on the ethernet interface
- can always be pinged.
-
- What is going on?
