Dear Cisco Fans and Professionals, I need some friendly advice. There are different opinions about Cat6500(High availibility with Single Router Mode) and (High availibility with Dual MSFC Redundancy)
Imagine you had 3 Cat65007s with Dual MSFC1 and Dual Supervisor1A. That is 6 MSFC's and 6 Supervisor engines. You have over 1500 users to support with 30VLANs that need interconnecting routing via EIGRP. Some user applications are sensitive to packet loss. You have to provide minimium downtime in the case of MSFC failer or Supervisor failer. Question 1. Which would you implement (High availibility with Single router mode) or (High availibility with Dual MSFC Redundancy) and why? Question 2. Is was brought to my attention that running dual MSFC redundancy with a high number of VLANS would cause the EIGRP process to run very high. As you know EIGRP is a very noisy protocol. Query storms.. Implementing EIGRP passive interface on all VLAN interfaces except the management VLAN would help the EIGRP process to run low. Are query storms an issue to worry about even after the passive interface is issued on client/user VLANS?
