Help. I've got a 1720 router with T1-WIC, that I'm trying to configure for a Covad T1. Covad gave me a config, but my router doesn't recognize many of the commands that as I know are standard in IOS. I have even reset to factory and upgraded to IOS 12.4(17a) and still no joy.

here is what Covad sent me;

end

None of the MMI commands are recognized and I'm going nuts. Any help would be great.

Thanks,
 
does it not connect? Those mmi configs are defaults. What specific problems are you having?

Thanks for replying,
the router doesnt accept the commands at all. when I do a lookup via "m?" mmi is no where to be found. here is the output preceded by a "sh ver".

Thanks again,
 
What I am saying is that those commands are not necessarily important. Do this...
router>en
router#erase start
router#reload
Then it reloads. Then...
router>en
router#conf t
router(config)#int fa0
router(config-if)#ip add x.x.x.x 255.255.255.224
router(config-if)#no shut
router(config-if)#no keep
router(config-if)#exi

router(config-if)#no shut
router(config-if)#exi
router(config)#int s0/0.1 point-to-point
router(config-if)#frame-relay interface-dlci 16 ppp virtual-template 1
router(config-if)#no shut
router(config-if)#exi
router(config)#int virtual-tem 1
router(config-if)#ip add neg
router(config-if)#ppp chap hostname xxxxxxx
router(config-if)#ppp chap pass xxxxxxxxx
router(config-if)#ppp icpc wins req
router(config-if)#ppp ipcp dns req
router(config-if)#ppp ipcp route def
router(config-if)#ppp ipcp add acc
router(config-if)#no shut
router(config-if)#exi
router(config)#ip classless
router(config)#line con 0
router(config-line)#logg sync
router(config-line)#pass xxxxxxxxx
router(config-line)#login
router(config-line)#exi
router(config)#line vty 0 4
router(config-line)#pass xxxxxxxxxx
router(config-line)#login
and if you want to only use ssh to remote in instead of telnet, then...
router(config-line)#trans input ssh
router(config-line)#end
router#wr
That should get you started. Post the output of
router#sh run
after you have entered these commands. The "x.x.x.x" is your own IP address (LAN), and the "xxxxxxxx" are your own passwords.

Thanks for the help. I input the config as you've written, after connecting the router up it did sync. I dont know why I cant ping directly from the router, but traffic is flowing back and forth. I input my nbar config and its working like a charm.

Thanks for your help Burt, hope i can return the assistance someday.
 
A star maybe?lol
What do you mean...you cannot ping from the router?
Post your new config.

Burt
 
Sorry for my absence. Its been a rough week.
What I mean is that from the root router prompt, i cant just ping out. I have to select an interface, FE0 infact to ping internet IP's. I'm thinking its because I dont have a global route entry? Here is the new config, let me know what you think.

Thanks again for your help,

First, you have to explain what the serail interface is connected to and what the fa interface is connected to.

Burt

 
Yikes, forgot about that one.

S0 = ISP T1 connection to internet

FE0 = Local Interface to firewall running NAT
 
ip route 0.0.0.0 0.0.0.0 s0
or
ip route 0.0.0.0 0.0.0.0 s0.1

Burt
 
I thought the same, just haven't implemented the command since I havent been there. Thanks again Burt, I really appreciate all your help.
