Protecting an EBGP peer when memory usage reaches level 2 threshold
Memory usage includes the following threshold levels: normal, level 1, level 2, and level 3. When the level 2 threshold is reached, BGP periodically tears down an EBGP session to release memory resources until the memory usage falls below the level 2 threshold. You can configure this feature to avoid tearing down the EBGP session with a specific EBGP peer when the memory usage reaches the level 2 threshold.
For more information about memory usage thresholds, see Fundamentals Configuration Guide.
To configure BGP to protect an EBGP peer or peer group when the memory usage reaches level 2 threshold (IPv4):
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter BGP view or BGP-VPN instance view. |
| N/A |
3. Configure BGP to protect an EBGP peer or peer group when the memory usage reaches level 2 threshold. | peer { group-name | ip-address } low-memory-exempt | By default, BGP periodically tears down an EBGP session to release memory resources when level 2 threshold is reached. |
To configure BGP to protect an EBGP peer or peer group when the memory usage reaches level 2 threshold (IPv6):
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter BGP view or BGP-VPN instance view. |
| N/A |
3. Configure BGP to protect an EBGP peer or peer group when the memory usage reaches level 2 threshold. | peer { group-name | ipv6-address } low-memory-exempt | By default, BGP tears down an EBGP session to release memory resources periodically when level 2 threshold is reached. |
