[c-nsp] OSPF to ISIS migartion

[jack daniels]

Hi all ,
I have got a project for an ISP ( also LDP configured ) runnning OSPF to
migrate to IS-IS.
I was planning to runnn dual IGP , as ospf with AD 110 and ISIS with AD 115
, OSPF will always be preffered.
I was planning the challenges for migration, below are the ones which I
could think of , please give your inputs on WHAT CONSIDERATIONS TO KEEP IN
MIND BEFORE MIGRATION.
Also request you to share some docs for migration of OSPF to ISIS<<<<<

1)  MEMORY/CPU utilisation
2)  no. of routes in routing table and database
3)  harware of the cisco devices ( 7206/12K)
