Default
When the memory usage reaches level 2 threshold, BGP tears down an EBGP session to release memory
resources periodically.

Parameters
group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer
group must have been created.
ip-address: Specifies a peer by its IP address. The peer must have been created.
ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created.
Usage guidelines
Memory usage includes the following levels of thresholds: normal, level 1, level 2, and level 3. When
level 2 threshold is reached, BGP tears down an EBGP session to release memory resources periodically
until the memory usage is exempt from level 2 threshold. You can use this command to avoid tearing
down the BGP session with a specific EBGP peer when memory usage reaches level 2 threshold.
For more information about thresholds, see Fundamentals Configuration Guide.
Examples
# In BGP view, configure BGP to protect EBGP peer 1.1.1.1 when the memory usage reaches level 2
threshold.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer 1.1.1.1 as-number 200
[Sysname-bgp] peer 1.1.1.1 low-memory-exempt
# In BGP-VPN instance view, configure BGP to protect EBGP peer 1.1.1.1 when the memory usage reaches
level 2 threshold.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer 1.1.1.1 as-number 200
[Sysname-bgp-vpn1] peer 1.1.1.1 low-memory-exempt
peer next-hop-local
Use peer next-hop-local to specify a router as the next hop for routes sent to a peer or peer group.
Use undo peer next-hop-local to restore the default.
Syntax
In BGP IPv4 unicast instance view/BGP-VPN IPv4 unicast instance view:
peer { group-name | ip-address } next-hop-local
undo peer { group-name | ip-address } next-hop-local
