HP Comware 5 Debug Manual Vol 1

Parameters
ipv4-address: Specifies the IPv4 address of a peer.
ipv6-address: Specifies the IPv6 address of a peer.
Usage guidelines
This command enables all BGP debugging, which might cause heavy traffic and decrease system
performance. Therefore, use this command only when necessary.
Disable debugging after the debugging operation is complete.
Examples
# Display BGP configuration on Device A and Device B.
[Sysname-bgp]display this
#
bgp 100
undo synchronization
peer 10.1.1.2 as-number 100

# Enable all BGP debugging on Device A. While Device A and Device B are establishing an IBGP peer
relationship with each other, output similar to the following example is generated:
