Hi
I have problem with one serial lines.
The link it worked properly, but when I try to use the ppp reliable-link
command in the serial line configuration, the link is going down, and then
it's never becomme up with initial configuration.
On the other side I don't have in configuration this line:
ppp reliable-link
This is the configuration:
Cisco 7513
interface Serial9/5
bandwidth 64
ip address 193.231.142.41 255.255.255.252
encapsulation ppp
no ip mroute-cache
keepalive 20
no peer default ip address
no fair-queue
no cdp enable
end
Cisco 2610:
interface Serial0/0
bandwidth 64
ip address 193.231.142.42 255.255.255.252
no ip directed-broadcast
encapsulation ppp
keepalive 20
no fair-queue
The problem was when I put on the 7513 the ppp reliable-link command in
configuration.
I listed here the debug ppp negociation on the 7513 side:

try putting "no cdp enable" command in serial interface of both the routers,
let me know if it works

The solution was no encapsulation ppp, and I use the hdlc encapsulation.
I try with disabled cdp but it's not worked.
Anyway thx :)
