 Need help on ppp config on Cisco 2600 router
Cisco 2600, Cisco Routers, multilink, Point-to-point protocol, PPP, Routers
We are upgrading our point-to-point private line from single T1 to two T1 lines. I have installed the DSU/CSU module to the router. Working on the new configuration but found the ppp code I put in doesn't work. I can't figure out what was wrong. If you could give me a hand, that would be very very appreciated.

Here is the configration for both routers:

=========================================== WT-RT1# interface Multilink1 ip address 192.168.1.2 255.255.255.252 no cdp enable ppp chap hostname P2PWT ppp multilink ppp multilink fragment disable ppp multilink group 1 ! interface FastEthernet0/0 description LAN IF TO WT ip address 172.16.1.34 255.255.252.0 duplex auto speed auto ! interface Serial0/0 no ip address encapsulation ppp shutdown no fair-queue ppp chap hostname P2PWT ppp multilink ppp multilink group 1 ! interface Serial0/1 no ip address encapsulation ppp shutdown no fair-queue ppp chap hostname P2PWT ppp multilink ppp multilink group 1 =========================================== SF-RT1# interface Multilink1 ip address 192.168.1.1 255.255.255.252 no cdp enable ppp chap hostname P2PSF ppp multilink ppp multilink fragment disable ppp multilink group 1 ! interface FastEthernet0/0 description LAN IF TO SF ip address 172.16.8.2 255.255.252.0 duplex auto speed auto ! interface Serial0/0 no ip address encapsulation ppp no fair-queue ppp chap hostname P2PSF ppp multilink ppp multilink group 1 ! interface Serial0/1 no ip address encapsulation ppp ppp chap hostname P2PSF ppp multilink ppp multilink group 1 ===========================================
