known peer(s) + +A typical run configuration for a nwaku node is to connect to existing peers with known listening addresses using the `--staticnode` option. +The `--staticnode` option can be repeated for each peer you want to connect to on startup. +This is also useful if you want to run several nwaku instances locally +and therefore know the listening addresses of all peers. + +As an example, consider a nwaku node that connects to two known peers +on the same local host (with IP `0.0.0.0`) +with TCP ports `60002` and `60003`, +and peer IDs `16Uiu2HAkzjwwgEAXfeGNMKFPSpc6vGBRqCdTLG5q3Gmk2v4pQw7H` and `16Uiu2HAmFBA7LGtwY5WVVikdmXVo3cKLqkmvVtuDu63fe8safeQJ` respectively. +The Discovery v5 routing table can similarly be bootstrapped using a
