You must configure GTSM on both the local and peer devices, and you can specify different hop-count
values in a valid range for them.
Examples
# In BGP view, configure GTSM for BGP peer group test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test ttl-security hops 1
# In BGP-VPN instance view, configure GTSM for BGP peer group test.
<Sysname> system-view
[Sysname] bgp 100
