To achieve redudancy you can run HSRP between the two 2600s. If you do this, at a time, only one T1 will be utilised ( the T1 on the active 2600) while the other T1 will be used as backup. (for this you need to enable HSRP interface tracking).
IF 2600a lan ip add is 10.10.10.1, and 2600b lan ip add is 10.10.10.2, choose, 10.10.10.3 as the HSRP virtual ip. On the 7200, use a static default route as follows,
ip route 0.0.0.0 0.0.0.0 10.10.10.3
Run RIP v1 between the school access routers and 7200 and 2600s.
To achieve redundacy through HSRP I am well aware of that possibility. But I want to be able to utilize both T1s at the same time with load balancing but am unsure if this is done through static routing. In addition to utilizing both T1s, I would also like to have some sort of redundacy in case one of the T1s go downs. Is this possible. Thanks in advance.
I've never actually done this but here's how I understand it. You're best bet would be to run a routing protocol that would allow load balancing between equal cost paths (OSPF) or unequal cost paths (EIGRP). Since you can't run a routing protocol, you could configure 2 static routes on you're router with the same admin distance. Your router should load balance equally between the two links on outbound traffic. The route on the other end will also require 2 static routes back to you for inbound traffic. However, you're return traffic may not load balance equally. If the router is running CEF, it should always send traffic to the same destination out the same interface. In other words, traffic for 1 host on your network will not be devided between the links. Makes sense?
These articles should explain it a little more. Don't worry about the routing protocol part, you can replace it with static routes if you have too. Check out:
advertise static routes from 2600a and 2600b with same metric
7204 will have both routes in its routing table and will round robin between the two T1's on a per-destination basis
This will work as long as it is router to router communication.
If you have access clients on the LAN between the 2600's and the 7204, you will have to use multiple instances of HSRP and point different groups of users to the different instance of HSRP( poor mans load balancing) for hosts on that segment. Of course, you would track the T1 in order to fail over when the T1 went down.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
