Lab3 - A few Queries
Need to seek some expertise on the following tasks for Lab3. Any kind replies will be much appreciated.
Task 4.8 - RIPv2 (Do not enable RIP on any other
(Q1.) "passive-interface" is used on both R5
and SW1. If there any reason why "passive-interface"is NOT configured
(Q2.) Also do i have to put "no passive-interface
loopback0" on SW1 since loopback0 is to be advertised into RIP?
Task 4.9 - IGP Redistribution
(Q1.) Where is there a need to reduce the RIP distance
from 120 to 109? Since there is no multiple mutual redistribution between RIP
and OSPF domains. Suboptimal routing is not going to happen. I noticed this is
practised in Lab2 also, is this some kind of best practice for a "Bigger
Distance Routing Protocol" to be redistributed into a "Smaller
Distance Routing Protocol" even it is just only a single point of mutual
(Q2.) R5 should route thru R1 to get to prefixes learned
from BB1. R5 should route thru R2 to get to prefixes learned from BB3.
Besides the solution given by IE. Can i do the followings
ways, have tested it and it works.
(Read this on Brian’s
Method 1 – Apply summary address on both R2 (smaller
prefix of BB1 routes)and R1 (smaller prefix of BB3 routes)
Method2 – Change the admin distance of the OSPF routes to
255 originated by R1(matches BB3 routes) and R2 (matches BB1 routes) on R5
Task8.1 - Frame
Relay Traffic Shaping
map-class frame-relay FRTS
frame-relay bc 32000
(Q1.) For calculation, do I always assume the intervals
is standard of 8? Which gives a Tc of 125ms?
Formula is Bc/Tc
Bc/125ms = 256000 ; assume Tc is using 8
Task8.3 – Rate Limiting
Task – In order to attempt to improve
VoIP performance, configure the client applications on these VLANS to request bandwidth reservations of the network in the
(Q1.) Does the traffic needs to match ‘udp’ 1st before configuring “ip rvsp
bandwidth” since the objective is to improve VoIP performance?
(Q1.) Where to find this command “frame-relay
interface-dlci 555 protocol ip 188.8.131.52”? Even under CCO ‘AutoInstall
over Frame Relay-ATM Interworking Connections’, cant find this command
