I just do some test and found it is OK, here is my setup
R1-e0----cat---f0.1-------R8-e0--cat--e2/0-R5
R2-e0/0--cat f0.2-------R8
R3-e0/0--cat f0.3--bvi2-R8
R4-e0/0--cat f0.4--bvi2-R8
Cat port to f0 of R8 is set up as trunk for Vlan 1, 81-84. No problem at
all.

Subject: Tricky Bridging question?
Given the config below which came Rivron Francois on a post last week.
I have a router sitting on interface fa0.3, which is going through a
Cat5505. This router called "SAN-FRAN" has any IP address on its
interface connecting to fa0.3 I cannot ping past the BVI interface which
as an IP address in the same range as the BVI has SAN-FRAN's Ethernet.
Any ideas?
One proposition:
Assume that stations on vlan 3 & 4 have their ip @ in network 1
interface fa0.2
encap isl 2
ip ad <network 2>
interface fa0.3
encap isl 3
bridge-group 1
interface fa0.4
encap isl 4
bridge-group 1
interface bvi 1
ip ad <network 1>
bridge 1 route ip
bridge 1 protocol ieee
