I am having an issues programming my 2911 router with a hwic-4t1/e1 card for three bonded t1's with ppp.
Both the router and the Hwic are fresh out of the box. I have a very simple setup. I have 3 bonded leased t1 lines through AT&T to Time Warner Telecom's router using xxx.xxx.xxx.x45 on their end and xxx.xxx.xxx.x46 for my end.
I installed the Hwic and then did these commands to enable and set up to work with theirs like i was told:
(Basic....)
>enable
#config t
g)#hostname main
g)#no ip domain-lookup
(SSH...)
g)#username <username> password <pw>
g)#ip domain-name main.com
g)#crypto key generate rsa
g)#512
g)#ip ssh ver 2
g)#line vty 0 5
line)#login local
line)#transport input ssh
line)#exit
(install hwic)
g)#card type t1
g)#network-clock-participate wic 0
(config hwic controllers)
g)#controller T1 0/0/0
er)#faming esf
er)#linecode b8zs
er)#Fdl att
er)#clock source line
er)#loopback remote esf line
er)#cablelength short 110
er)#crc-threshold 320
er)#no yellow detection
er)#exit (repeated for 0/0/1 and 0/0/2)
(internal interfaces)
g)#int g0/0
f)#ip address 10.0.0.254 255.25.255.0
f)#no shut
(Destination of last resort)
g)#ip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.x45
(multilink ppp)
g)#int multilink 1
f)#ip add xxx.xxx.xxx.x46 255.255.255.252 (I get a error here saying it overlaps with a static route in the route table.)(so it wont accept it)
f)#no cdp enable
f)#ppp multilink
f)#ppp multilink group 1
f)#exit
(Adding interfaces to multilink group 1)
g)#int T1 0/0/0 (I get an error here saying invalid input at 1st 0 of 0/0/0) (So i tried "int T1 ?" and all i get is <cr> so I tried "interface ?" to see all possible interfaces and all i get are :
Async, Auto-template, BVI, CDMA-Ix, CTunnel, Dialer, Embedded-service-engine, GigE, Group async, LongReachEthernet, loopback, MFR, Multilink, Null, Port-channel, Pseudowire, Tunnel, VIF, Virtual-PPP, Virtual-Template, Virtual-TokenrRing, range, vmi
-At this point I dont know what to do?? I had planned on:
g)#int T1 0/0/0
f)#no ip address
f)#encap PPP
f)#no fair-queue
f)#ppp multilink
f)#ppp multilink group 1
f)#exit
(repeated for 0/0/1 and 0/0/2 but obviously if i can't get into the interface config i can't set these commands)
-So i went on to nat....
g)#access-list 5 permit 10.0.0.0 0.0.0.255
g)#ip nat inside source list 5 interface T1 0/0/0 overload (obviously this didn't work, so I tried "ip nat inside source list 5 interface t1 overload")
-It took but it I think it has something to do with ??tunnel?? (I dont really understand tunnels)
g)#int g0/0
f)#ip nat inside
f)#exit
g)#int T1 0/0/0 (again didn't work so I used "int T1" and it took)
f)#ip nat outside
f)# exit

In each controller interface add "channel-group 0 timeslots 1-24"
This will create serial interfaces. Configure each as
No ip addr
Encap PPP
PPP multilink
PPP multilink group 1
On int multilink 1 add your IP address, PPP multilink and ppp multilink group 1

On each controller interface you need a channel group. That command creates the serial interfaces you need to join into the multi link group.

Thanks Jeff that got my serial interface to show up!
But I am still having the problem with my IP address on my multilink interface. Whenever I enter the ip address command i get an error saying that the ip address conflicts with the static routes. I checked the routing table and the only thing that shows is on g0/0 my connected 10.0.0.0/24? I don't understand what the conflict is. Do I need to look elsewhere for an issue?

It may just be a typo but the subnet mask on g0/0 is off.

Also if you have any addresses on any interface other than g0/0 or multilink 1, remove them. And your in nat outside needs to be in the multilink interface as well as the nat statement.
