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 unicast/multicast address family):
