Best multilink configuration?

[xenolith]

I have a customer who is about to come online using 2 T1s in multilink. He sent me his configuration to look over. I am not sure why he is setting up multilink in this manner. Here is the relevant config:

interface Loopback0
ip address 192.168.1.42 255.255.255.252
!
interface Serial0/0
no ip address
encapsulation ppp
pulse-time 1
ppp multilink
!
interface Serial 0/1
no ip address
encapsulation ppp
pulse-time 1
ppp multilink
!
interface Virtual-Template1
ip unnumbered Loopback0
ppp multilink
!
ip route 0.0.0.0 0.0.0.0 192.168.1.41



Typically I see multilink setup as:

interface Multilink1
ip address 192.168.1.42 255.255.255.252
ppp multilink
ppp multilink links maximum 2
ppp multilink links minimum 1
ppp multilink group 1
!
interface Serial0/0
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1
!
interface Serial0/1
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1
!
ip route 0.0.0.0 0.0.0.0 192.168.1.41

I was wondering which was the better multilink setup? Is my customer on to something I am not aware of or way off base?

Thanks,
Josh

In my opinion your customer's config is incomplete - your version looks much better.

Thats kinda what I thought as well. I have made my recommendations to my customer regarding the multilink setup. I had another customer sometime back who setup multilink with virtual-template but it seemed to cause them problems trying to bring the logical interface up. Hopefully they will just go with the more conventional setup, but it's their choice now.

Thanks,
