I95-62982 is critical for the 6.3.7 release notes
** I95-62982 SSR limits the number of supported network-interfaces: Improved implementation of data structure storing network-interface objects, increasing capacity. For the SSR1300, the number of network-interfaces has been increased from 2100 to 4300.

| - **I95-62956 Configuration failure due to invalid name:** The CSRX does not allow policynames using a dot (.). This has been resolved - CSRX configurations will use an underscore for policyname creation. | ||
| ------ | ||
| - **I95-62982 SSR limits the number of supported network-interfaces:** Resolved an issue where the limit on the number of network-interfaces was low. Improved implementation of data structure storing network-interface objects, resulting in an increase of 2x the current capacity. |

Please update this issue to the following language, as engineering has completed their scalability testing:
- I95-62982 SSR limits the number of supported network-interfaces: Resolved an issue where the limit on the number of network-interfaces was low. Improved implementation of data structure storing network-interface objects, resulting in an increase of 7x the current capacity.

| - Rx Timer: Local router expects to receive an async packet from the peer before the end of each timer. Set based on max value of local `required-min-rx-interval` and peer’s `desired-tx-interval`. Updated after first received BFD packet. | ||
|
|
||
| - Tx Timer: Configured value under d`esired-tx-interval`, no negotiation involved. One async packet is sent at the end of each Tx Timer. |
