Invoking zebra

Besides the common invocation options (See also Common Invocation Options) there are zebra specific invocation options below.

-b
--batch
Runs in batch mode. zebra parses configuration file and terminates immediately.
-k
--keep_kernel
When zebra starts up, dont delete old self inserted routes.
-l
--log-mode
Set verbose logging on.
-r

When program terminates, retain routes added by zebra.

Interface Commands

Command: interface IFNAME
- Interface Command: shutdown
- Interface Command: no shutdown
  Up or down the current interface.
- Interface Command: ip address ADDRESS
  Set ip address for the interface.
- Interface Command: description DESCRIPTION ...
  Set description for the interface.
- Interface Command: multicast
- Interface Command: no multicast
  Enable or disables multicast flag for the interface.
- Interface Command: bandwidth <1-10000000>
- Interface Command: no bandwidth <1-10000000>
  Set bandwidth value for the interface. This is for calculating OSPF cost. This command does not set actual device configuration.

Static Route Commands

Command: table TABLENO
Select the primary kernel routing table to be used. This only works for kernels supporting multiple routing tables (like Linux 2.2.x).
Command: ip route NETWORK GATEWAY
Command: ipv6 route NETWORK GATEWAY

zebra Terminal Mode Commands

Command: show ip route
Display current routes which zebra holds in its database.

          Router# show ip route
          Codes: K - kernel route, C - connected, S - static, R - RIP,
                 B - BGP * - FIB route.
          
          K* 0.0.0.0/0              203.181.89.241
          S  0.0.0.0/0              203.181.89.1
          C* 127.0.0.0/8            lo
          C* 203.181.89.240/28      eth0

Command: show ipv6 route
Command: show interface
Command: show ipforward
Display whether the host's IP forwarding function is enabled or not. Almost any UNIX kernel can be configured with IP forwarding disabled. If so, the box can't work as a router.
Command: show ipv6forward
Display whether the host's IP v6 forwarding is enabled or not.
