IP subnet across IB subnets ?
Lack of IB support
- scope bits
- routing protocol
- port to router interaction (in CA hardware ?)
- Multicasting (intra and inter IB subnet)
- router discovery/redirects (become ICMP?)
- complex address resolution
Prefer Last Call of March 2002
- IB upgrades aren’t less complex than we think!!
Recommend: IP subnets don’t span IB subnets
