We have two internet service providers ISP1 and ISP2. We have two 1841 series routers on which these links are terminated. Now we are in phase of purchasing "IP address Pool" which is routeable by all IPS's so that it will be routed by both the ISPs and our rosources will be available all the time even if ISP1 or ISP2 link is down. Here is the problem , ISP 1 and ISP 2 are asking us to RUN BGP on our routers. We have 1841 series routers and running BGP on it will be too high expection. Is it possible to run a very samll / limited version of BPG ( similar to OSPF stub area ) on this router ( 128 mb dram , and Adv. Secruity. Enterprise version of IOS is available on router ). What I feel is that can we have a simple static routing done for the same pool from both the service providers and we will use interface tracking to send the traffic either to ISP1 or ISP2.
Purchasing 3845 or 3825 series router will be too costly.
Please share experience.
Thanks in advance
