Hi every1, this query could be a bit long but kindly read it, its very imp. I have a 3845 router running 12.4 20T, with 64 flash and 512 ram. Its utilization on average is 52% !!. This router is the DMVPN hub for 40 branches, other branches are coming through other P2p links. The number of branches is 160. The hub router is also connected to internet and from the entire country the traffic lands on this router to reach internet and other branches for data connectivity. On this 3845 i just have onboard encryption card and no AIM or other modules. Now an evaluation team proposed us that if we run MPLS in our environment with our ISP we will achieve the following
1) More guaranteed and end to end QOS for mission critical applications.
2) Bandwith management will be better
3) CPU utilization will drop.
For point 3) they said that due to use of gre tunnels router has to do a lot of fragmentation which results in high cpu load !!.
I am seeking advice from you experts kindly guide me, is it wise to run mpls in my bank ??? how will it benefit me ? shall i really go for it ? i think mpls is very complex to configure and understand so what you guys think. Pls provide me some basis so that i may know whether its really gonna be helpful or a burden ??
Thanks in advance
