What is DisableIPSourceRouting?

MSS: (DisableIPSourceRouting) IP source routing protection level (protect against packet spoofing)- The Policy Expert. The objective of this kind of attack is to flood the target with an overwhelming volume of traffic when the attacker does not care about receiving responses to the attack packet.

Should I disable source routing?

(Source routing is an IP option that allows the packet to specify the route it should take to its destination.) Source routing is a potential security problem, so it is best to disable this feature unless required.

What is the use of IP source routing?

Source routing is a feature of the IP protocol which allows the sender of a packet to specify which route the packet should take on the way to its destination (and on the way back). Source routing was originally designed to be used when a host did not have proper default routes in its routing table.

What is IP forward protocol ND?

The ip forward-protocol nd command simply means that the router will forward ND packets for diskless workstations. This is rather obsolete. The ip http commands are for the HTTP server in the router itself. It is a way to configure the router with HTTP, and it means nothing to anything else connected to the router.

What is IP CEF Cisco command?

Cisco Express Forwarding, CEF is advanced Layer 3 IP switching technology used on cisco router and switch. It is a feature that allows a router to quickly and efficiently make a route lookup. CEF optimizes routing table lookup by creating a special, easily searched tree structure based on the IP routing table.

What is IP Multicast routing?

IP multicast routing enables a host (source) to send packets to a group of hosts (receivers) anywhere within the IP network by using a special form of IP address called the IP multicast group address.

What is IP forwarding Cisco?

IP forwarding, or IP routing, is simply the process of receiving an IP packet, making a decision of where to send the packet next, and then forwarding the packet. The forwarding process needs to be relatively simple, or at least streamlined, for a router to forward large volumes of packets.

Is IP a forwarding protocol?

The IP forwarding algorithm is a specific implementation of routing for IP networks. In order to achieve a successful transfer of data, the algorithm uses a routing table to select a next-hop router as the next destination for a datagram. The IP address of the selected router is known as the next-hop address.

How do I know if my CEF is enabled?

To confirm that CEF is enabled globally, issue the show ip cef command from the user EXEC or privileged EXEC mode. The show ip cef command displays the entries in the Forwarding Information Base (FIB). If CEF is not running, the %CEF not running message appears instead.

How do you test a CEF table?

The details are correct. The next step is to verify the next-hop CEF entry for 10.18. 118.184, which is 172.18. 114.1….

Step 1	Verify the CEF configuration.
Step 2	Confirm the IP CEF switching path, including using CEF accounting counters to confirm the switching path.
Step 3	Verify CEF switching details.

What are the protocols used in multicast?

Multicast protocols such as UDP/IP and RTP/IP are used to broadcast data to any number of receiving devices. Unlike unicast TCP data, if a packet is not received, there is no mechanism or attempt to verify that and resend the packet. Multicast is widely used for video and audio data.
