EIGRP
network IP netmask ->
netmask is a must to stop “auto summery” even while using “no auto” !!!
manual neighbors
sh ip eigrp nei
manual ->
router eigrp 100
neighbor 208.102.37.100 f1/0
sh run
sh ip pro
sh ip eigrp nei -> will not show this new neighbor !
Other end should point to me using a “neigbor command”
Redistribution Eigrp
1.ip route 0.0.0.0 0.0.0.0 f0/0 (scott)
router eigrp 100
redist static defaultmetric
2.int f1/0 (scott)
ip summery address eigrp 100 0.0.0.0 0.0.0.0
this will be sent to the neighbors as the default route
3.ip route 0.0.0.0 0.0.0.0 f0/0 (Jeremy)
router eigrp 100
net 0.0.0.0
Load balancing
default 4 equal cost paths
1.equal cost
maximum path 1-6
2.unequal cost
variance
cost based packet allocation, e.g costs 1 & 4
router eigrp 100
traffic share min -> use min cost links
traffic share balanced -> back to cost based allocation
BGP
in Ibgp-> peers do not need to be directly connected tcp/179
Ebgp multihop
