Hi ,
Here is a design scenario:
Distribution 4605 4605
| |
L3 L3
| |
Core :--- 6509A sup720 --- ISL ---- sup720 6509A
--------------- L3 Etherchannel ------
| |
| |
L3 L3
| |
Distribution 4605 4605
I have 2 core switches connected to more than four 4605 distribution switches and I have routed links between them.
The distribution switches are in turn connected via 802.1Q trunks to 3550 access switches.
I have a ISL trunk between the 2 core sup 720 engines .
The links to the distribution switches all have a ospf cost of 10.
The L3 etherchannel between the core have a ospf cost of 5
Is this a good design in terms of load balancing and redundancy for a campus network ?
Any comments and input much appreciated
Thanks,
Paul
