To make your life harder you will be asked to redistribute.

If using authentication define authentication keys under relevant interfaces.

Enable Rip updates authentication and whether it should beД®ncrypted (MD5 mode) or clear text (text mode).

Decide whether you want auto-summarization or not.

Exclude some interfaces from active advertising RIP on them but allow to get.

Specify networks RIP protocol will be active for.

Dictate the version to work with вЂ“ RIP v1 or RIP v2.

As I come up with new ideas how to break the RIP on ASA I will update this article as well.ДЄs it would be expected ASA has a bit limited version of RIP daemon as compared with IOS one. RIP has been with ASA for years and in this article I will try to cover all possible scenarios in configuring, misconfiguring.

Redundant interfaces are compatible with fail over feature.

Redundant interface gets by default MAC address of the first added to it interface, configurable.

Only one interface is passing production traffic at any given moment.

All the interfaces in the same group should be of the same type (Ethernet with Fiber wonвЂ™t go well).

You can define up to 8 Redundant interfaces (if you have ASA 5580 why not?).

Having done a bit practice the dry theory comes next.

(If you want to read the IP routing tables on a Windows 95/98 workstation, type ROUTE PRINT in the DOS box.)Д¤. After determining which direction to forward the packet, the router must build a new header. Routers maintain a routing table that lists available networks, the direction to the desired network (the outgoing interface number), and the distance to those networks. A router cannot decrement the TTL value to 1 and then forward the packet.ДЈ. If an IP packet has a TTL value of 1, the router discards the packet. Unlike the IPX hop count, which increments as the packet is forwarded through each router, the IP TTL value decrements as the IP packet is forwarded through each router. IP headers contain a Time to Live (TTL) value. If a packet has a hop count of 15, the router discards the packet.

By default, 15 hops is the maximum number of hops (or routers) that a packet can cross. For example, IPX headers contain a hop count. The router must ensure that the packet has not come too far to be forwarded. The router then strips off the MAC header and examines the network-layer header to determine what to do with the packet.Дў.

The router checks the packet for MAC-layer errors. Check the incoming packet for corruption, and remove the MAC header. After receiving the packets, the router must perform the following steps:ДЎ. Local devices address packets to the routerвЂ™s MAC address in the MAC header. These network-layer headers contain source and destination network addresses. Routers make forwarding decisions based on the packetвЂ™s network-layer header (such as an IPX header or IP header). Whereas switches can only examine and forward packets based on the contents of the MAC header, routers can look further into the packet to discover the network for which a packet is destined.
