Action

To configure the tracing for sent or received BGP protocol packets, follow these steps:

1. In configuration mode, go to the following hierarchy level:

[edit]

2. Configure the flag to display sent, received, or both sent and received packet information:

[edit protocols bgp traceoptions]

user@host# set flag update send

or

[edit protocols bgp traceoptions]

user@host# set flag update receive

or

[edit protocols bgp traceoptions]

user@host# set flag update

3. Verify the configuration:

user@host# show

For example:

[edit protocols bgp traceoptions]

user@host# show 

file bgplog size 10k files 10;

flag update send;

or

[edit protocols bgp traceoptions]

user@host# show 

file bgplog size 10k files 10;

flag update receive;

or

[edit protocols bgp traceoptions]

user@host# show 

file bgplog size 10k files 10;

flag update send receive;

4. Commit the configuration:

user@host# commit
