EIGRP:
router eigrp 100
	network x.x.x.x
	variance (unequal load-balancing, esim 2 x feasible distance)

EIGRP stub:
int
	ip summary eigrp 100 x x (haluttuun routeriin menevään inttiin)
router eigrp 100
	eigrp stub
	(redistribute static jos static)

EIGRP named:
eigrp -> address-family ipv4 unicast autonomous-system 4

OSPF virtual links:
interfaceihin ip ospf network point-to-point jos haluat loopbackin olevan network eikä 1 host
clear ip ospf 1 process jos id ei vaihdu

networkit area 0
networkit area 2
networkit area 3

virtual linkin luominen area 3 -> 0
router ospf 1
area 2(väliarea) virtual link (vastaanottavareititin)
ospf
	area 3 range x.x.x.x x.x.x.x

default routen mainostaminen
ospf -> default-info orig always

MULTI-AREA OSPF:
interfaceihin voi laittaa ip ospf 1 area 0 sen sijasta että konffaa sen ospf
static route toiseen networkkiin: ip route x.x.x.x x.x.x.x output ip
	redistribute static subnets
ospf -> area 2 stub molempiin routereihin, tai area 2 stub no-summary jos haluat totally stubby (pelkkä 1 default route)

OSPF EIGRP REDIST:
router eigrp 1
no auto-summary
networkit

ulosmenevään inttiin voi laittaa ip summary-add eigrp 1 x.x.x.x x.x.x.x summaryt

ospf:lle point-to-pointit intteihin loopback
ospf networkit

routerille, joka on molemmissa -
router ospf 1
	redist eigrp 1 subnets
