MHSRP & DHCP

Hi Guys,

 

I think this is an interesting scenario.

 

rtr-x rtr-y

  |-----------| <--vlan 10

 

 

 

Requirement: Configure the rtr's such that the hosts on vlan 10 split their
traffic approx 50/50 between the rtr's.

 

If one of the rtr's fails, the other router should handle all the traffic,
but when the failed router comes back into service,

 

the traffic should again be split 50/50.

 

 

Partial Solution:

 

Configure dhcp on both routers and config mhsrp.

 

Questions:

 

1) Assuming both routers are up, what determines which of dhcp server hands
out ip addresses when a PC powers up?

 

2) If one of the routers is down for a while, the other dhcp server on the
other server will be handing out ip addresses. If a lot of

 

PC's power up during that period or have to renew their dhcp lease, they'll
all end up using the up router as their gateway. Is there any way

 

to make such that after the failed router comes back up, the traffic load
will be well balanced?

 

 

TIA, Tim
