Multiple IP blocks in an "ip local pool" - cisco 3640
Posted on 2004-10-25
Cisco 3640 terminating remote connections;
Currently we assign IP addresses via radius packets, issuing the IP address for that user from the local pool (local pool defined, but RADIUS controls which IP each connection gets).
ip unnumbered FastEthernet3/0
no ip redirects
no ip proxy-arp
ip mtu 1492
peer default ip address pool myippool
ppp authentication pap chap
ppp ipcp mask 255.255.255.128
ip local pool myippool 192.168.227.5 192.168.227.126
ip route 0.0.0.0 0.0.0.0 192.168.141.33
no ip http server
We have almost run out of issuable IP addresses for the current IP block listed in "myippool". We have another non-contiguous IP block (192.168.56.128/26) which is currently terminating at this router, and partially used for a dedicated connection.
description customer VLAN serial
encapsulation isl 45
ip address 192.168.56.137 255.255.255.248
no ip redirects
no ip route-cache
no ip mroute-cache
no cdp enable
we would like to use some of those remaining IP addresses in "myippool" so that we can issue them out to other connections as we do with the current IPs in "myippool".
Have tried just assigning one of the IP addresses to an end client without the IP addresses being listed in "myippool" and routing does not take place (connected, authenticated, IP sent, no routing).
Getting one large block and reassigning IP addresses to everyone isn't a feasible option since the usage of IP addresses is in a dedicated manner for most connections.
