covad PPPoFR. no default GW. why?

[ldmccalla]

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.

[ldmccalla]

the command is entered but it won't stick in the running config.

[paolo bevilacqua]

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]

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]

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]

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

Please remove "ip address negotiated" from interface Virtual-Template1.

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

-Rakesh

[ldmccalla]

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]

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]

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]

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]

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 · Accepted solution]

I'm referring to:

ip local pool default 10.10.10.10 10.10.10.11

About which you have not reported.
