可以在 /etc/iproute2/rt_tables 文件定义路由表(ip routing table)id以及它的别名
Route tables: Linux-2.x can pack routes into several routing tables identified by a number in the range from 1 to 2^32-1 or by name from the file /etc/iproute2/rt_tables By default all normal routes are inserted into the main table (ID 254) and the kernel only uses this table when calculating routes. Values (0, 253, 254, and 255) are reserved for built-in use.
Command to list all ip route tables in linux kernel
ip route show table all
ip route show table all | grep "table" | sed 's/.*\(table.*\)/\1/g' | awk '{print $2}' | sort | uniq
ip route show table all | grep -Po 'table \K[^\s]+' | sort -u
