BGP Session Builder

Describe a neighbor once, then generate configs for any vendor from the Vendor Config Generator using the same values.

Session Parameters

Local ASN

Remote ASN

Router ID

Neighbor IP

Description

MD5 Password (optional)

Session Type

Multihop TTL (0 = direct/eBGP-multihop off)

Update Source (loopback, optional)

Max Prefix Limit

Keepalive (s)

Hold Time (s)

Address Families

IPv4 Unicast

IPv6 Unicast

BFD

Graceful Restart

Prefixes to Advertise used for network / address-list / firewall statements

IPv4 Prefixes (one per line)

IPv6 Prefixes (one per line)

These populate the network / output.network advertisement statements, the null/discard aggregate routes, and the owned-prefix firewall address-lists in the Vendor Config Generator — for both IPv4 and IPv6.

Vendor Config Generator

Generates a working BGP neighbor configuration from the session parameters above. Review before deploying — always test in a maintenance window.

Prefix Filter Generator

Filter Input

Min Length (ge)

Max Length (le)

Bogon & Martian Reference

RFC1918, RFC5737, RFC6598 CGNAT, loopback, link-local, multicast, and reserved ranges that should never be accepted from an eBGP peer.

Route Policy Builder

Compose match/set rules visually, then export as a route-map / policy-statement.

Policy Rule

Match: Prefix-list

Match: AS-Path (regex, optional)

Set: Local Preference

Set: MED

Set: Community (add)

Output Cisco / JunOS / MikroTik style

Fill the form and click Build Policy.

Local Preference & MED Cheat Sheet

Value	Typical use
200	Preferred primary transit / preferred peer
150	Secondary transit
120	Customer routes (usually highest in real designs)
100	Default / unset
80	Backup-only path, de-prioritized

Higher Local Preference always wins first, before AS-Path length, before MED. Set it deliberately on every inbound policy rather than leaving it at the default.

Config Validator

Paste a router config snippet. Runs heuristic checks for common BGP misconfigurations — not a substitute for a lab test.

IRR Registries

Registry	Scope	Object types

RIPE NCC	Europe, Middle East, Central Asia	route, route6, as-set, aut-num, route-set
APNIC	Asia Pacific (incl. Pakistan via PKNIC)	route, route6, aut-num
ARIN	North America	route, route6 (via RADB/ARIN-WHOIS)
LACNIC	Latin America & Caribbean	route, route6, aut-num
AFRINIC	Africa	route, route6, aut-num

Register a route / route6 object for AS64500's originated prefixes so upstreams building bgpq4/bgpq3 filters (an as-set like AS-YOURNAME) will accept your announcements.
