DNS fails w/ static route to BVI

[MWM]

827 help appreciated.
Using static ip from PacBell--connects using IRB just fine, but I have to assign a static route to the gateway address for DNS to work. Shouldn't it work as well using the BVI 1 interface?

----Static route 0.0.0.0/0 to BVI 1 cannot ping DNS server.
Static route 0.0.0.0/0 to 63.192.xxx.xxx, the PacBell gateway, does connect to DNS; this works.
The Static Route command synatx allows both the Bridge Virtual Interface and the Forwarding Router Address, but only the Forwarding Router Address works. Why?

Also, "IP Name-Server" command seems redundant since there is a dhcp command, "DNS-Server"? DNS works fine using only the dhcp DNS-Server command.

And, is there any syntax significance between "BVI 1" (with a space) and "BVI1" (without a space)?
