This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
Keepalive and hold decide how fast a silent peer is declared down. Dampening suppresses a route that flaps. The calculators show the arithmetic. They do not open a session. A hold shorter than three keepalives is a number you recheck against the platform.
Dampening on a route you originate can hide your own prefix from the internet. Write that risk. One session you administer, named only so the later window knows where the draft would go.
Do not apply the timers. Do not add a neighbor.
The change you can finish
Apply nothing during the writing of the note. When the lab window opens, it is one change on the device named in the ticket. Read the draft, then the device, then decide.
Rollback is the file or the revision you saved first. You do not invent a rollback after the only copy is gone.
- Write keepalive and hold.
- Say whether dampening is in scope.
- If it is, write what a flap would hide.
- Do not apply either.
- Do not add a neighbor.
- Stop.
Mistakes that outlive the command
BGP Timers and Route Dampening goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A hold the peer does not share.
- Dampening that hides your own prefix with no sentence.
- Applying the draft.
- A new neighbor.
- A session you do not administer.
Decisions to write down
One decision for BGP Timers and Route Dampening: The timers match the peer on paper. Dampening risk is written or dampening is out. Nothing was applied. No neighbor was added. And the session is yours.
Checks before you call it done
Confirm this before you call the change done: Keepalive is written. Hold is written. Dampening is yes or no. No session was changed. And no neighbor was added. If one of those fails, stop.
Before you leave the device
BGP Timers and Route Dampening ends when the hostname on the device matches the hostname in the ticket. If it does not, you are on the wrong box. Stop. A command that succeeded on the wrong box is not progress.
The draft stays a draft until a person has read the names in it. A generator does not log into the device and does not know which interface is the uplink. You delete a line that names a device, a zone, or a prefix you did not write down.
0.0.0.0/0 is not kept because a sample included it. A source you can say is the source you keep. 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. They belong in the note. They are not prefixes you type onto a production device because they appeared in a draft.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, a community string, or a pre-shared key you save in the ticket or in git. The real secret stays in the store.
One change is the window. A VLAN and a routing protocol and a VPN do not share it. If two things move and the result is wrong, you will not know which one did it. The next feature waits for its own page.
If the same step fails twice, stop for the day. The failure is the result. Adding a forum command beside a half-applied config produces a device nobody can rebuild. Restore the copy you took first.
A second person reads the device name and the change aloud. If they cannot find them in the ticket, the note is not done. Silence is not agreement. Then leave the device alone.
This page is a planning guide. It is not a vendor manual, not an official standard, and not a permission to touch a network you do not administer. The pillar guide owns the wider design. This page owns one lab proof.
