BGP的CASE题，一共四道，自己答的，应该错了两道；

其中一个是BGP的as-path与route-map的acl匹配进行路由过滤；还有一个是IPv6的loopback接口的EIGRP路由问题，别的想不起来了，呵呵

154TK中，下面这段描述很有用，我没怎么看，但出来后，发现BGP的CASE变种，跟这个有点相似，提醒大家注意！！！

+ s6 Q+ d- P4 ~0 W, S* WNew BGP question:
First question is about BGP, involving only 3 of the routers of the topology
+ B" H9 b; N- C, F' qR1 ------ R2 -------R3
Shows u the routing table of R1 and partial BGP configuration. R1 Routing Table has 3
routes, one of them is matched by an access list applied to a community setting for
neighbor R2. This community is NOT ADVERTISE, which means that the router
receiving this route (R2) can use it, but not advertise it to any neighbor. The question
2 o4 a; _) e+ ~is, which routes will R3 have on its BGP table after this. I was wrong and choose the
option that it will only have the other 2 routes, because I supposed that the question
) G3 r9 p. M! ]was related to communities, but I tell you what I really think; R3 will have any of the
routes since both three are iBGP peers ( no sync is on R1 config and it is supposed to be
configured the same in all the AS) Dont let this confuse u. iBGP peers do not advertise
each other routes even if syncronization is disabled (the only way to do it is with route
4 o. G7 c+ {- t8 u* breflectors or confederations) So, my conclusion for the routing question is that no
routes will reach R3 BGP table.
" [1 n5 ?, V/ w' I( v4 E4 B6 E5 jSecond question is about IPV6 multicast.( Over the lan link between two routers)
1 T3 E+ N. Q5 i% `Shows you Mroute entry and gives several options. Right answers are that the multicast
group in the shared tree is FFF0:0002 (or whatever I dont remember but u should
check it on the (*. XXXX)
, `) C5 a; d2 W( {and the second answer is that a route to the RP has been pruned, which can be
' @; v" G# T/ h( s1 Qconfirmed by checking the flags SPC (sparse mode, connected, pruned)
Third question is about QOS. Shows u some markings by packet lenght. Options are
8 ?/ T' c8 L7 n6 Othat the firrst class is marking packets which size is between 500 and 1500 bytes, which
is RIGHT. Second option is that second class is marking packets with size of 500 with ip
1 M; ^7 E& X# J9 v2 Aprecendence 3 which is not wrong, because altouhg one of the condifions is lenght=
500, thsa class statement is a MATCH ALL and there is also another condition
regardiong DSCP, so paket lengh is not enough for marlking here. This option is WRONG.
% I4 D2 j" S; J$ l7 iThird option is that one of the clases is marking packets with size = 200 and this is true.
Fourth question is about ipv6 eigrp. over the same lan segment, shows loopbak
" B- S) H& x' \/ Tinterfaces running eigrpV3, everythig n is ok and pings dont work. The right option is
that u have to configure eigrp process on each router (doing it in only one is not enough)
This is true because Eigrpv6 needs a no shut under the process to work!

" g1 k) r1 h  a+ ?2 z: w我是因为这个原因，所以才着急考笔试的！免得给自己找麻烦，呵呵！！！

暂时不想考证，积累经验和打好基础再讲。
