customer needs to have a redundant cme setup in his environment.
his present config is ccm 3.0 on a 2600 series router. this router also connects his remote branch through a leased line.
connected to this router is a 3550 cat switch with two fibre modules connecting back to two other cat switches. on one of these switches is connected another 2600 series with a T1 connected to their legacy PBX system (mix if PBX and IPT).
now he just bought a 2811 voice router. he wants to have it as a spare for obvious reasons.
im thinking of configuring HSRP but im not too clear as where to start. ive been doing the reading but still not quite clear. here are my issues:
do i configure hsrp on the switch or on both routers?.
what about routes? at present he has static routes on the router as well as the switches(vlans 2 data 3 voice and doing intervlan routing).
the gateway for the clients are at present the router. id like to leave that ip address so i wouldnt have to make any major changes to the network. now, i understand that ill be configuring a virtual address but then ill have to configure other addresses on the router as well as change the static routes throughout the network?
sorry it looks like im confused. any help will be appreciated. in the mean time ill do some more research. i know it should be simple, and from the documentation i understand the theory....
the two routers will be placed for connectivity to the remote sites only. im running ccme only on the current router and the other has the same configuration , software and hardware in the event of "hardware" failure. we are not doing any type of load balancing etc.
switch is EMI. and there is also another 3550 on the other side that is also EMI.
TOPOLOGY IS CORRECT, my concern is with remote side connection only for ccme redundancy
to sum up, two routers connecting to 3550 EMI. ip phones also connected to this switch. in the event of failure of one router would like to cut over to standby router that has same configuration and components. (NO LOAD Balancing to be done therefore only one group to be configured)
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
