Multihomed BGP and HSRP (again)
Posted on 2005-04-20
This questions has seemed to be asked and answered but not exactly to my understanding...(my fault I am sure)
I currently have 1 x 3 meg connection to the internet. We are using BGP because that was the way it was when I took over management. We own a class c network which is announced via bpg to our ISP.
We are getting a new 3.0 meg connection from a different ISP on a different local loop for redundancy. Each ISP will be terminated on its own 7206xvr. Here is how it will look...
| | (3 meg each) (Using MFR and MPPP to combine 2 T1's)
RTRA---iGP---RTRB (Routers are both 7206XVR with 256 of mem)
Core Switch (Nortel Passport - soon to be 6509)
| | |
Dist Switch SRV SRV
My concerns are redundancy, automatic failover, load balancing.
I am confused between HSRP and GLBP.
Sorry about asking this question yet again but this seems to be a popular subject and I want to make sure that there is a clear answer.
I have also seen where I can stagger the announcements to do some outbound load balancing as well as some BGP tweaks to control manipulate inbound traffic.
Any thoughts on this would be appreicated.
