how to configure 8192 bridge domain default limit shows 2048

Hello,

 How can i scale up bridge-domain from 2048 to 8192.

 As per the link (http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-1/lxvpn/configuration/guide/lesc41/lesc41p2mps.html) ASR9000 series routers can scale up to 8192 bridge-domains.

 However my ASR9k shows the l2vpn capability to be only around 2048. How can i configure 8192 bridge-domain

Are there any LC scale profiles configured in the admin mode? If so, that would reduce L2 resources. If you don't need the L3 profile, remove it and reboot the router to gain back 8k bridge domains.
