Hello,

 I need to move server from one office to another, but need to save it's IP
 address. The configuration (one two routers) is:

 Router in the previous office (where server was):

 bridge irb
 bridge 1 proto ieee
 bridge 1 route ip
 !
 int Fa0/0.2
  descr Server was there
  encap isl 2
  bridge-group 1
 !
 int ATM0/0.301
  descr Link to new office
  pvc 0/301
   encap aal5snap
  bridge-group 1
  mtu 1500
 !
 int BVI 1
  descr Rest (in the first office) servers
  ip address x.x.x.x 255.255.255.224

 and router in the second office (where server will be):

 bridge 1 proto ieee
 !
 int Fa2/0.108
  descr Server will be there
  encap isl 108
  bridge-group 1
 !
 int ATM1/0.301
  descr Link to previous office
  pvc 0/301
   encap aal5snap
  bridge-group 1
  mtu 1500

 Launch of this server in the new office was unsuccessfull - it doesn't
 ping. First router show me:

Router-1#show bridge

Total of 300 station blocks, 289 free
Codes: P - permanent, S - self

Bridge Group 1:

    Address Action Interface Age RX count TX count
00d0.b717.0203 forward Fa0/0.2 0 210990 199791
00d0.b760.d6cc forward Fa0/0.2 0 1821 1721
0090.272f.84b5 forward Fa0/0.2 0 26573820 23610908
0090.2735.0130 forward Fa0/0.2 0 1929680 1020155
00d0.b76a.e4ab forward Fa0/0.2 0 4753084 3725178
0090.272f.84e6 forward Fa0/0.2 0 471342 565534
00d0.b70c.2e5d forward Fa0/0.2 0 684178 866803
0800.20a2.2aa1 forward Fa0/0.2 0 32971 44034
0004.dd9e.55c0 forward Fa0/0.2 1 27 27
0800.207f.e226 forward Fa0/0.2 0 500855 1389836
0090.27a2.22d0 forward Fa0/0.2 0 5363521 4913652

 interesting, that interface ATM0/0.301 doesn't take a part in the process.
 And second router shows:

Router-2#sh bridge

Total of 300 station blocks, 299 free
Codes: P - permanent, S - self

Bridge Group 1:

    Address Action Interface Age RX count TX count
0090.272f.84b5 forward ATM0/0.301 0 34 0

 There isn't Fa2/0.108 in this result. What is cause? Where I'm wrong?

 And another issue - is BVI always eats CPU resources so much?

 Thank you.
