Maximum EVC bridge-domain?

[david.sua]

Hi ciscomates!

Somebody knows if there is a limitation in bridge-domain under service instance?

I have a Cisco 7606S with WS-SUP720-3B, 7600-SIP-400 and SPA-5X1GE-V2

I have a config like this,

interface GigabitEthernet3/3/4
mtu 9216
no ip address
negotiation auto
service instance 101 ethernet
encapsulation dot1q 1034 second-dot1q 4
rewrite ingress tag pop 2 symmetric
bridge-domain 15 split-horizon
!

But after 120 service-instance with brigge domain I have this error,

%bridge-domain rejected: unable to allocate port

Somebody can help me?

Thanks in advance.

Hello David

Are you using VPLS or EoMPLS circuits with EVC towards the AC's.

if yes, then the max that can be configured on SIP-400 card is 120. Please refer to the below CCO documentation for reference.

Hope this answers your question.
