- We've had the same symptom for a while but attributed it to our use of
- secondary addresses. On the same cable, we have three Cisco's with
- consistent subnet addresses, except one of them has a primary address
- in a different subnet than the other two. Our Sun logging station is
- addresses in the "common" subnet, so it complains about RIP updates it
- receives that are sourced with the primary address in the other subnet.

- Sec #1 Net.117.x Net.117.x Net.4.x
- Sec #2 Net.204.x Net.204.x Net.204.x

- If the R3 situation weren't temporary, we'd just swap the first two above;
- we expect this would silence the Sun.
