- Probably a good idea since the example in your book shows it like this. The

- Not really. What I want to do is route area 12 of USBR domain through USGS
- domain. It isn't important whether area 12 is a seperate domain or not unless
- it causes problems.

- I don't understand why. All nodes on the ethernets are Phase IV, the only place
- Phase V exists is on the cisco's.

- I do not want, and when we go live can NOT have, Phase IV adjacency. What I want
- is Phase conversion on the cisco's. The global WAN (USBR) routing Phase V on
- cisco's and the local WAN (Mid Pacific Region - MP) routing Phase IV on all
- kinds of stuff.
