Victor,
Have you looked at the RFC to help get an understanding (RFC
3021 - Using 31-Bit Prefixes on IPv4 Point-to-Point Links)?

Subject: Use of the 31-Bit Prefixe in a P2P Link
Hello All, sorry for this dummy question, but could any one please
explain the use of the 31-Bit Prefixe in a P2P Link
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft
/122t/122t2/ft31addr.htm
Im trying to configure a P2P Link with a Frame-relay encapsulation, but
I think that I do not understand the addressing scheme,
R1 s0/0 ----- Transparent Line ------ s0/0/0 R2
On R1:
Interface serial 0/0
Encapsualtion frame-relay
No keepalive
No ip address
no shut
Clock rate 64000
Interface serial 0/0.1 point-to-pint
Ip address 172.16.78.0 255.255.255.254
Frame-relay interface-dlci 1
Interface serial 0/0.2 point-to-pint
Ip address 172.16.78.2 255.255.255.254
Frame-relay interface-dlci 2
On R2:
Interface serial 0/0/0
Encapsualtion frame-relay
No keepalive
no shut
No ip address
Interface serial 0/0/0.1 point-to-pint
Ip address 172.16.78.1 255.255.255.254
Frame-relay interface-dlci 1
Interface serial 0/0.2 point-to-pint
Ip address 172.16.78.3 255.255.255.254
Frame-relay interface-dlci 2
Do this only works for this kind of interfaces? Where we can use the
whole /30 as a bundle or there is another freaking application for this?
Thanks
Victor.
