Solved: Re: covad PPPoFR. no default GW. why? - Page 2

ldmccalla · ‎05-23-2009

according to the docs this config below should work but i don't seem to have a default route installed. whats worse is that i cannot add a static route to the virtual-access interface that gets built after the passwords are accepted.

Right, an explicit address is not allowed on an virtual interface, to prevent multiple assigments.

Go ahead and configure a pool

ip local pool default 10.10.10.10 10.10.10.11

and use pool in peer default ip address

All this in the hope of finally providing the remote with a valid address.

paolo bevilacqua · ‎05-25-2009

Have you configured the pool ?

Can you take the ppp trace again ?

It may not stick due to using the default pool.

For sure you're meeting a lot of undue difficulties.

paolo bevilacqua · ‎05-24-2009

Also very strange is how the router keeps sending CONFreq before finally accepting the reply more than one minute later.

But, let's see if you resolve the connectivity problem first.

rakesh.hegde · ‎05-25-2009

Hi,

Your configuration looks good. Can you please try the following configuration ?

interface Virtual-Template1

no ip address

ppp multilink

ppp multilink group 1

ppp chap hostname xxxx

ppp chap password 0 yyyy

interface Multilink1

ip address negotiated

ppp ipcp route default

ppp ipcp dns request

ppp multilink

ppp multilink group 1

If you still dont see the default route, add a static default ponting to Multilink1 interface

HTH,

Rakesh

ldmccalla · ‎05-25-2009

not that i haven't tried this already but this was indeed a valiant attempt. the problem is that Multilink1 does NOT get assigned an IP. "Virtual-Access 1" is created with the IP and so that's where i need to route my data to. when i point the default GW to multilink 1 the result is the same as when i pointed the default GW to Serial 0/0:1.1. In that situation, the static route never made it to the route table because the interface does NOT have an IP.

i need to be able to set the default gw to "Virtual-Access 1"

PS i also tried using a route-map to force all traffic to "virtual-Template 1" and that didn't help

Have you bounced your serial interface to re-initiate PPP negotiation ? If so, its time to call the TAC I guess.

-Rakesh

ldmccalla · ‎05-25-2009

yes i bounce the controller.

the whole reason i'm here is bacause my 1760 is EOL and so TAC won't renew the service contract.

Cisco refuses to take my money.

Leon

rakesh.hegde · ‎05-25-2009

Can you please trun on "debug ppp negotiation" ? Do a shut/no shut on ser 0/0 and post the output . Also,please post sh ip int brief.

-Rakesh

ldmccalla · ‎05-25-2009

there is a debug with my original config attached to my post at "May 24, 2009, 12:54pm PST". here is the debug with multilink and without ip negotiation.

Leon

paolo bevilacqua · ‎05-25-2009

Have you tried with pool configured ?

May 24 15:52:00.070: Vi1 IPCP: I CONFREQ [REQsent] id 1 len 10

May 24 15:52:00.074: Vi1 IPCP: Address 0.0.0.0 (0x030600000000)

May 24 15:52:00.074: Vi1 IPCP: Cannot satisfy pool request

May 24 15:52:00.074: Vi1 IPCP: Neither side knows remote address

ldmccalla · ‎05-26-2009

see my "May 24, 2009, 7:01pm PST" post. the command is entered but it does not stay in the config when i do show run it is not there.

how can i get TAC to help? they won't take my money because my 1760 is EOL but this is clearly an IOS issue. I'm sure a brand new 1801 would fail. if i plug the Covad Netopia in, it works just fine.

paolo bevilacqua · ‎05-26-2009

I'm referring to:

ip local pool default 10.10.10.10 10.10.10.11

About which you have not reported.
