[c-nsp] 7600-ES20 L2 and L3 Multiplexing

[Antonio Soares]

Hello group,

I received some off-line help and now i have a workaround:

+++++++++++++++++++++++++
 !
 service instance 200 ethernet
  encapsulation dot1q 200 second-dot1q 100
  rewrite ingress tag pop 2 symmetric
  bridge-domain 200
 !
!
interface Vlan200
 ip address 20.20.20.254 255.255.255.0
 ipv6 address 2001:20::2/64
!
+++++++++++++++++++++++++

Now there is a document about the ES20 that says the following:

"Flexible QinQ Mapping and Service Awareness on 7600-ESM-2X10GE and 7600-ESM-20X1GE is supported only through Ethernet Virtual
Connection Services (EVCS) service instances."

"The Flexible QinQ Mapping and Service Awareness on 7600-ESM-2X10GE and 7600-ESM-20X1GE feature allows service providers to offer
triple-play services, residential internet access from a DSLAM, and business Layer 2 and Layer 3 VPN by providing for termination of
double-tagged dot1q frames onto a Layer 3 subinterface at the access node."

I still do not understand if L3 sub-interfaces are supported or not and if they are, why IPv6 commands are not accepted.


Thanks.

Hello group,

I have a ES20 interface configured with L2 services via the "service instance" command. Now i would like to add L3 services to the
same physical interface but i noticed a problem with IPv6:

7600#
7600#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
7600(config)#!
7600(config)#interface GigabitEthernet3/0/0.200100
7600(config-subif)# encapsulation dot1Q 200 second-dot1q 100
7600(config-subif)# ip address 20.20.20.254 255.255.255.0
7600(config-subif)# ipv6 address 2001:20::2/64
                       ^
% Invalid input detected at '^' marker.
 
7600(config-subif)#ipv6 ?    
% Unrecognized command
7600(config-subif)#

After removing all the service instance entries, the IPv6 command was accepted. Is this a known limitation ? I saw the same problem
with 12.2(33)SRC2 and 122-33.SRD2a.


Thanks.
