You can view that GTSM is enabled, the valid hop count is 1, and the BGP connection is in the
Established state.
Step 9 Configure GTSM on Switch B and Switch D. Switch B and Switch D are connected by Switch
C, so the range of the TTL value between the two switches is [254, 255]. The value of valid-ttl-
hops is 2.
# Configure GTSM of the IBGP connection on Switch B.
[SwitchB-bgp] peer 4.4.4.9 valid-ttl-hops 2
# Configure GTSM on Switch D.
[SwitchD-bgp] peer 2.2.2.9 valid-ttl-hops 2
# Check the GTSM configuration.
