What does ip source-route do?
What does ip source-route do?
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 the use of no ip source-route?
–> During an attack, an attacker could use source routing to direct packets to bypass existing security restrictions. –> Use the ‘no ip source-route’ command to disable IP source routing on the Cisco router.
What is no ip source-route command?
Use the ‘no ip source-route’ command to disable IP source routing on the router.
How do you prevent source routing?
Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “MSS: (DisableIPSourceRouting) IP source routing protection level (protects against packet spoofing)” to “Highest protection, source routing is completely disabled”.
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 ICMP redirect?
An ICMP redirect message is an out-of-band message that is designed to inform a host of a more optimal route through a network, but possibly used maliciously for attacks that redirect traffic to a specific system.
What is Martian logging?
A Martian packet is an IP packet seen on the public Internet that contains a source or destination address that is reserved for special-use by Internet Assigned Numbers Authority (IANA). The name is derived from packet from Mars, meaning that packet seems to be not of this Earth.
How do I disable my IP routing?
To enable IP routing, use the ip routing command in switch configuration mode. To disable IP routing, use the no form of this command. This command has no arguments or keywords.
What is IP verify?
What is Verification IP? Verification IP (VIP) blocks are inserted into the testbench for a design to check the operation of protocols and interfaces, both discretely and in combination. Most standard protocol and interface IP enables verification engineers to check basic features, such as system start-up.
Should I disable ICMP redirect?
If an attacker is able to forge ICMP redirect packets, he or she can alter the routing tables on the host and possibly subvert the security of the host by causing traffic to flow via a path you didn’t intend. It’s strongly recommended to disable ICMP Redirect Acceptance to protect your server from this hole.
What is interface configuration mode for Cisco Nexus 5000?
Enters interface configuration mode for the primary VLAN. Isolated and community VLANs are both called secondary VLANs. Maps the secondary VLANs to the Layer 3 VLAN interface of a primary VLAN to allow Layer 3 switching of private VLAN ingress traffic.

Where are VRFs located in Cisco Nexus 7000?
VRFs exist within virtual device contexts (VDCs). By default, Cisco NX-OS places you in the default VDC and default VRF unle ss you specifically configure another VDC and VRF. For more information, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 5.x .
How to remove static route in Cisco Nexus 7000?
Use the no { ip | ipv6 } static-route command to remove the static route. You can configure a static route in a VRF. Ensure that you are in the correct VDC (or use the switchto vdc command). 3. ip route { ip-prefix | ip-addr ip-mask } { next-hop | nh-prefix | interface } [ name nexthop-name] [ tag tag-value] [ pref ]
