ppp over serial problem :(

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:

Re: ppp over serial problem :(

The solution was no encapsulation ppp, and I use the hdlc encapsulation.

I try with disabled cdp but it's not worked.

Anyway thx :)
