I have a small question about ospf I know that unicast, multicast and hello packets have 1 ttl ttl but if a packet with TTL 60 comes from a different geographic continent and my border router ospf enabled, what should happen?
The edge router will forward on the IP target written in the IP datagram? I guess so, it is a router and It will make his job. The question arose reading this topic: [1]http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory /cisco-sa-20130801-lsaospf In the topic published by cisco The packet crafted have to know some info: such as the network placement and IP address of the target router LSA DB sequence numbers, and the router ID of the OSPF Designated Router (DR) however in the absence of mechanisms to spoof and MD5 authentication, the IP packet will be rotated correctly toward the target?
