Configure Cisco 1721 2 T1's PPP multilink

[ceplon]

Greetings. I will be adding a second T1 to our network. I read here (

http://www.tek-tips.com/viewthread.cfm?qid=1245003&page=1)

and other sites that the best way to bond them is using the Multilink PPP.

I just want to make sure my configuration is correct. PLease let me know if there is anything wrong or missing.

Here is the info from my ISP

--> General Circuit Information <--
===================================

Enter the following in global config:

ip cef
service password-encryption

Add to multilink interface:

no cdp enable
ppp multilink fragment disable

I would also enable NTP for correctly dated logging information. Following is an example of pacific time settings that self adjust for daylight savings time:


service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
service sequence-numbers
logging buffered 51200 debugging
clock timezone Pacific -8
clock summer-time Pacific recurring
ntp server xxx.xxx.xxx.xxx

BTW....
The correct subnet mask for your ethernet port should be 255.255.255.128
