Re: Interview Questions!

HSRP MAC fix part: 0000.0c07.ac

conver ip in to mac: use http://www.cisco.com/warp/public/cc/techno/tity/prodlit/ipmlt_wp.htm

noramlly 25bit are fix mac(0x0100.5E) and other are the last 23 bits of the multicast Ip address

lsa 9 10 and 11 are known as Opaque lsa

LSA type 9 are link-local scope; they are not flooded beyond the local (sub) network.

LSA type 10 are area-local scope; they are not flooded beyond the borders of their associated area.

LSA type 11 are AS scope; they are flooded throughout the entire AS. Their scope are equivalent to the flooding scope of AS-external (type 5) LSAs. Then, they are not flooded into stub areas.
