How can I give a Linux routing table an alphabetic name?

  • 772

The ip command only allows numeric table names. But I see that some default tables exist with alphabetic names (local, main). Is there a way to give it an alphabetic alias?

    Add it to /etc/iproute2/rt_tables for iproute2 and to /etc/systemd/networkd.conf for systemd. (The initial tables are defined in /usr/share/iproute2 for the former, and hardcoded for the latter.)

    /etc/iproute2/rt_tables
    
1      arpanet
2      dn42

# Reserved
253    default
254    main
255    local

    /etc/systemd/networkd.conf.d/tables.conf
    
[Network]
RouteTable=1:arpanet
RouteTable=2:dn42
