[c-nsp] High Availability PoP Design

[Mark Tohill]

Hi,

Consider the following:

| H1------S1----R1----ISP1
|    \    /\     /
|     \  /  \   /
|      \/    \ /
|      /\     \
|     /  \   / \
|    /    \ /   \
|  H2----- S2----R2----ISP1

H1/2 are dual-homed hosts.
S1/2 are WS-2970G-24's.
R1/2 are 7204VXR's with NPE-G1's connecting to redundant links in providers PoP.

Was hoping to implement HSRP but can this be implemented? The 2970's ( running Enterprise IOS) can't do layer 3 routing, right?

How would you connect redundant links to NPE-G1 gig ports and make them act like two switch ports?

Any advice appreciated.
