chp 2 static routing Flashcards
1
Q
routers can learn of remote networks by
A
- manually
- dynamically
2
Q
static routing advantages
A
- better security
- less bandwidth
- the path used is known
3
Q
when to use static routes
A
- small networks
- routing to and from stub networks
- connecting to specific network
- gateway of last resort
- reduce number of routes
- creating backup routes
4
Q
default static route
A
- matches all packets
- ip address to which the router sends all packets it does not have a route for
- all zeros as destination address
5
Q
summary static route
A
- summarizes contiguous networks into a single network address
- all use same exit interface or next hop ip
6
Q
floating static route
A
- backup route
- sits unused until primary link fails
- takes over for primary link
- has a higher administrative distance
7
Q
next hop options
A
-identified by ip address exit interface or both
8
Q
static route types
A
- next hop route
- directly connected static route
- fully specified static route
9
Q
next hop route
A
-only the next hop is specified
10
Q
directly connected static route
A
-only the exit interface is specified
11
Q
fully specified static route
A
- next hop ip is specified
- exit interface is specified
12
Q
static routing disadvantages
A
- configuration and maintenance is time consuming
- error prone
- network changes must be manually updated
- requires complete knowledge of network
- not scalable
13
Q
host routes
A
- automaticall installed when an ip address is configured on router
- marked with L in routing table
- ipv4 address with 32bit mask
- ipv6 address with 128bit mask
