Route Filter Generator

Paste IPv4 or IPv6 prefixes and generate reusable route-filter snippets for several common network OS formats.

Inline qualifiers such as “10.0.0.0/8 le 24” are supported.

Target Platform List Name Action

Prefix Input

Inputs

List of IPv4 or IPv6 prefixes, one per line
Inline qualifiers such as '10.0.0.0/8 le 24'
Target vendor (Cisco IOS, IOS-XR, Junos, Bird, FRR)
Action (permit / deny / accept / reject)
List name (used as the policy identifier)

Outputs

Vendor-specific prefix-list or route-filter snippet
Ready to paste into running config

Use Cases

Turnkey prefix-list for a new customer or peer
Rapid conversion between vendor dialects
Converting ad-hoc prefix lists into reviewable policy

Limitations

Runs fully in-browser; no config validation against a real device
Does not resolve AS-SETs — pair with AS-SET Expander for that workflow

Example Input

10.0.0.0/8 le 24
192.0.2.0/24

Example Output

ip prefix-list FILTER-LIST seq 5 permit 10.0.0.0/8 le 24
ip prefix-list FILTER-LIST seq 10 permit 192.0.2.0/24
