Lab2 - A few Queries
Just finished my Lab2. I have a few queries with regards to the answers given by IE. Cracked my brain and read through my notes, but still clueless
Task2.1 - Configure FR Full-mesh, do not use static L3-to-L2 mappings over FR connections
no frame-relay inverse-arp IP 105
no frame-relay inverse-arp IP 113
Qns : why cant we just use "no frame-relay inverse-arp"? which will takes precedence for both 'no frame-relay inverse-arp IP 105' and 'no frame-relay inverse-arp IP 113"
Task4.5 - Enable EIGRP between R2 and R6
router eigrp 10
network 18.104.22.168 0.0.0.0
network 22.214.171.124 0.0.0.0
Qns : How come R6's E0/0.26 is not advertised into EIGRP domain. Diagram shows R6's E0/0.26 is in EIGRP domain.
Task 4.6 - Configure R6 so that rest of routers in EIGRP domain have only one route to the prefixes learnt from BB1 with a 1st octet of 200.
Answer " ip summary-address eigrp 10 126.96.36.199 255.255.252.0 5"
Qns : Why is there a need to use an admin distance of 5 at the back?
Task 4.11 - Redistribute between RIP and OSPF on SW1
redistribute ospf 1 metric 1
Qns : Why is there a need to change the OSPF distance from 110 to 109 since there is only one router doing mutual redistribution, suboptimal routing will not occur. This is unlike the mutual redistribution (OSPF and EIGRP) that occurred on multiple routers such as R2, R3 and R4.
Task 9.3 - Traffic Logging
snmp-server community public RO 1
access-list 1 deny any log
Qns : how come access-list 1 is denying everything, isnt it supposed just to deny snmp traffic port 161? 'access-list 101 deny tcp any any eq 161 '
Task 10.1 - RMON
Answer : Uses absolute sampling for 'rmon alarm'
Qns : What is the keywords in the tasks that differentiate between absolute sampling (increases and decreases) from delta sampling (only increase)? Lab1 uses delta sampling, and the tasks are pretty similar to Lab2 tasks for RMON.
Any kind replies are much appreciated.
