remember that MSS determines max TCP msg size, while
window size determines HOW MUCH DATA A HOST CAN RECEIVE B4 IT REPLIES WITH AN ACK MSG. YES, THE TCP WINDOW SIZE IS MEANT TO TAKE IN SYN MSGS B4 IT CAN REPLY WITH AN ACK. SO YOU DON'T STALL WAITING FOR AN ACK MSG a b c d. ? HINT: REMEBER THAT CISCO IOS DEVS WILL CONFORM TO THE LOWER MSS VALUE.... a b c d e f. ? MSS LOWER WILL BE MATCHED......... a b c d. ? a b c d. ? hint: remember the default number of bytes for each header: ethernet: 14 ip: 20 GRE: 4 ip: 20 (yes, a GRE tunnel is encapsulated by 2 ip fields) TCP: 20 data: ? FCS: 4 it's ip traffic, so you can drop ethernet (14) and FCS (4) out of the equation. you're left with the default values for IP, GRE, IP,, and tcp: 1450 - 20 - 4 - 20 - 20 = 1386 a b c d. ? remember: for cisco devs: same net: 1460 different net: 536 a b c d. |
