Introduction to URPF TechnologyGenerally, after receiving the data packet, the router obtains the destination IP address in the data packet, searches the local routing forwarding table for the destination IP address, and forwards the data packet if there is a corresponding forwarding entry; otherwise, discards the packet. . From this point of view, when the router forwards the message, it does not care about the source address of the packet. This gives the source address spoofing attack a chance.The source address spoofing attack constructs a series of packets with the spoofed source address and frequently accesses the device or host where the destination address resides. Even if the response packet cannot reach the attacker, the attacker will cause a certain degree of damage to the attacked object.The main function of unicast reverse path forwarding (URPF) is to prevent network attack behavior based on source address spoofing. After the URPF function is enabled on the interface of the router, when the interface receives the data packet, it checks the legality of the source address of the data packet. The forwarding entry of the address enters the packet forwarding process; otherwise, the packet is discarded.Second, the working mechanism of URPFThe URPF checks the legality of the source address of the packet into strict (strict) and loose (loose) types:Strict-type URPF: not only requires the router to forward the table, but also has a route to the source address of the packet. It also requires that the inbound interface of the packet is the same as the outgoing interface to the source address. The message is considered to be a legitimate message. In some special cases (such as the existence of asymmetric paths), strict type checking will incorrectly discard non-attack messages.

Q1Which material is most helpful

Q2:which packets can help you find the cause


Demo2:

Customer just setup a IPv6 Network, with HSRPv6 on R1 & R2. After setting up, all hosts lose connection.

What would you recommend to your L1 Engineer as a Quick Fix?

CE1 key configuration

standby 1 priority 200

standby 1 preempt

ipv6 nd router-preference low

CE2 key configuration

standby 1 preempt

ipv6 nd router-preference high 

 

 

I think it is a rouge device because I don't see any problems with the HSRPv6 config. PCs are configured with "ipv6 enable", "ipv6 autoconfig"

The R1 have a "ipv6 nd-preference high" and R2 have "low" if I'm not wrong.

 

How fast fix the problem?

 

¡ Shutdown the link between CE2 and PE2.

¡ Shutdown the link between CE1 and PE1.

¡ Configure CE1 with highest HSRPv6 Priority.

¡ Configure CE2 with highest HSRPv6 pirority.

¡ Configure CE2 with low HSRPv6 priority.

¡ Shutdown CE1 interface e0/0.

¡ Shutdown PE2 interface e0/0.

¡ Disable fast-switching on CE's LAN.

¡ Enable fast-switching on CE's LAN.

¡ Change HSRPv1 to HSRPv2 version
