Have a few queries hope someone can clarify and advice.
Q1) Pls see attached file "Configuring EIGRP" page 1. Here's the extract "Increased network width-With IP RIP, the largest possible width of your network is 15 hops. When EIGRP is enabled, the largest possible width is 224 hops. Because the EIGRP metric is large enough to support thousands of hops, the only barrier to expanding the network is the transport layer hop counter. Cisco works around this problem by incrementing the transport control field only when an IP packet has traversed 15 routers and the next hop to the destination was learned by way of EIGRP. When a RIP route is being used as the next hop to the destination, the transport control field is incremented as usual."
Can some1 explain what the above means?
Am I right to interpret as follows
"Below 16 hops, even if EIGRP is enabled, the routers learn the shortest route by RIP way, that is hop.
Above 15 hops, (this is where RIP deems the destination unreachable) then the shortest route is learned by EIGRP metrics of bandwidth, delay, reliability, load, and maximum transmission unit."
Am I right or wrong?
Q2) Pls see attached file "EIGRP 16406" page 35 under section "Pacing Packets". Here's an extract "The default configuration for EIGRP is to use up to 50 percent of the available bandwidth, but this can be changed".
Can someone explain what this mean?
So, does it mean we have to modify the default value to something else?
What would be your suggested value?
Q3) Equal and non-equal load balancing and Feasible Successor, all calculated based on metrics bandwidth, delay, reliability, load, and maximum transmission unit. Right?
So the metric bandwidth, is it referring to the bandwidth of the interface on the router? Such as if it is a FE port, it will take the bandwidth as 100Mbps, regardless of whatever external device it is connected to?
Pls kindly and quickly revert.
