Hi ,
My router communicate with another router over serial link, with EIGRP.
The problem consist in EIGRP flapping and my backbone interface is up and
down, frecvently...

Last week I introduced a new VIP 4-80 controller in the router CISCO
7513(module 0) :
1 VIP4-80 RM7000 controller (1 FastEthernet)(4 Serial)(2 E1).
Controller Memory Size: 128 MBytes DRAM, 65536 KBytes SRAM
Fast-Ethernet PA, 1 ports, 100BaseTX-ISL
Fast-Serial PA, 4 ports (attention:PA 4T not PA 4T+)
This controllers not function properly with System Bootstrap, Version
11.1(8)CA1, and I proceed to install another bootstrap.
Now I have a new bootloader version 12.2(1) and with work much better.
IOS (tm) RSP Software (RSP-JK9SV-M), Version 12.2(3), RELEASE SOFTWARE
(fc1)
ROM: System Bootstrap, Version 11.1(8)CA1, EARLY DEPLOYMENT RELEASE

BOOTLDR: RSP Software (RSP-BOOT-M), Version 12.2(1), RELEASE SOFTWARE
(fc2)
I forget mention it, the backbone line is very full(bandwidth 6M) every
day and night, and mrtg graph don't have Gauss inflection.

Why not function properly the backbone links with VIP 4-80 with the PA
4T and the PA - 1FE ISL???
This PA 4T function with VIP 2-40
Thanks in advance.
