REP configuration on bridge domain

Hi All,

I have read ES+ configuration guide regarding configuring REP. Its stated that we can configure REP on a bridge domain


This example shows how to configure REP over EVC using bridge-domain.

Router# enable

Router# configure terminal 

Router(config)# interface gigabitEthernet 4/1

Router(config-if)# service instance 10 ethernet 

Router(config-if-srv)# encapsulation dot1q 10

Router(config-if-srv)# rewrite ingress tag pop 1 symmetric 

Router(config-if-srv)# bridge-domain 100

Router(config-if-srv)# exit

Router(config-if)# rep segment 2 edge

Router(config-if)# end

My question is why cant I configure this on my router:

KGD-NPE-01#sh version

KGD-NPE-01(config-if-srv)#  bridge-domain 2 split-horizon



KGD-NPE-01(config-if)#rep ?

% Unrecognized command

KGD-NPE-01(config-if)#rep segment 2 edge


% Invalid input detected at '^' marker.


Is there any software requirement for this to happen? As you can see, I am currently use SRD4.

Re: REP configuration on bridge domain

Hi Prima,

I can configure it on my device (with SRE4 though):

lan-7600-2(config-if)#interface GigabitEthernet7/1

lan-7600-2(config-if)#service instance 40 ethernet

lan-7600-2(config-if-srv)#encapsulation dot1q 333

lan-7600-2(config-if-srv)#rewrite ingress tag pop 1 symmetric

lan-7600-2(config-if-srv)#bridge-domain 32 split-horizon


lan-7600-2(config-if)#rep ?

  block    Block port & VLANs for VLAN Load-balancing

  preempt  Preemption options

  segment  REP segment ID

  stcn     Segment Topology Change Notification

Is your module 1 an ES+? Can you print a show module please?

If yes, can you try from scratch creating a new instance with new encapsulation?

REP configuration on bridge domain

Hi Ricardo,

Yes my module 1 is ES+ module, otherwise I can not configure EVC right? or there are other modules that can support EVC?

below is my show module:

KGD-NPE-01#sh module

Mod Ports Card Type                              Model              Serial No.

--- ----- -------------------------------------- ------------------ -----------

  1   20  7600 ES+                               7600-ES+20G3C      JAE14210EWU

  5    2  Route Switch Processor 720 (Active)    RSP720-3C-GE       JAE14190FDB

  6    2  Route Switch Processor 720 (Hot)       RSP720-3C-GE       JAE14190FT0

I think its because I use IOS version SRD4, while yours are using SRE4. what is your IOS train? mine is advanced IP services SSH.

REP configuration on bridge domain

same train.

Try to create a new service instance bridging to another vlan to see if the command is available. Or else try an upgrade.
