The characteristics of RIPv2 follow:
Distance-vector protocol.
Use UDP port 520.
Makes Automatic summarization on network Class boundary.
Classless protocol (supports VLSMs).
Have the power to shut the Auto-summarization And make a configured manual Summarization.
Supports VLSMs.
Metric is router hop count.
Maximum hop count is 15; infinite (unreachable) routes have a metric of 16.
Periodic route updates sent every 30 seconds to multicast address 224.0.0.9.
25 routes per RIP message (24 if authentication is used).
Invalid route marked after 180 sec.
Flush timer is 280 sec.
Hold-down timer 180 sec.
Supports authentication.
Implements split horizon with poison reverse.
Implements triggered updates.
Subnet mask included in route entry.
Administrative distance for RIPv2 is 120.
Used in small, flat networks or at the edge of larger networks.

The characteristics of EIGRP follow:
Hybrid routing protocol (distance vector that has link-state protocol characteristics).
Use DUAL, first proposed by E. W. Dijkstra and C. S. Scholten, to perform distributed shortest-path routing while maintaining freedom from loops at every instant. Although many researchers have contributed to the development of DUAL, the most prominent work is that of J. J. Garcia-Luna-Aceves.
Cisco Proprietary created in 1994.
First released in IOS 9.21
Uses IP protocol 88.
Makes Automatic summarization on network Class boundary.
Classless protocol (supports VLSM).
Have the power to shut the Auto-summarization And make a configured manual Summarization.
Default composite metric of bandwidth and delay.
You can factor load, MTU and reliability into the metric.
Eigrp metric is the same as IGRP*256, It uses the smallest B.W,Reliablity,Load & MTU with the Comulative delay upon the path…..The MTU doesn’t actually used in the Metric calculations,
But is included in the EIGRP Routing updates.
Sends route updates to multicast address 224.0.0.10, and nei. Reply’s back with Unicast Address.
Sends non-periodic, partial, and bounded updates.
Send Hello packets every 5 sec. and Hold down timer is 15 sec.
For Low speed Hello is every 60 sec. with hold down time 180 sec.
By default, EIGRP uses no more than 50 percent of the bandwidth of a link.
Support for authentication via MD5 Only.
Uses DUAL for loop prevention, and generating Succ./Fesible Succ.
Maximum paths for Load-balancing are 6 & default is 4 , maximum are 16 in IOS 12.3(2)T and later IOS releases
By default, Equal-Metric load balancing. If Unequal-Metric load sharing is used the router will load share inversely proportional to the metrics of the paths.
Administrative distance is 90 for EIGRP internal routes, 170 for EIGRP external routes, and 5 for EIGRP summary routes.
Potential routing protocol for the core of a network; used in large networks.
For neighbor relation to be established, both routers must send and receive Hello or Ack packets from each other, they must have the same AS #, and the same Metric K values.
Eigrp doesn’t restrict that neighbors must have the same Hello & dead interval timers, Unlike OSPF.
Has a Maximum hop count of 255, the default is 100 in the last IOS releases.

The characteristics of OSPF follow:
Link-state routing protocol.
Uses IP protocol 89.
Classless protocol (supports VLSMs and CIDR).
Metric is cost, based on interface bandwidth by default (10^8 / BW in bps).
Sends partial route updates only when there are changes.
Send hello packets every 10 sec with dead timer of 40 sec over P-P & BC networks.
Send hello packets every 30 sec with dead timer of 120 sec over NBMA networks.
If the network is stable and there have been no updates within 30 min, a compressed update is sent.
Routes labeled as intra-area, interarea, external Type 1, or external Type 2.
Support for authentication.
Uses Dijkstra algorithm to calculate SPF tree.
Default administrative distance is 110.
Uses multicast address 224.0.0.5 (ALLSPFRouters).
Uses multicast address 224.0.0.6 (ALLDRouters).
Recommended for large networks.
For 2 routers to be adjacent :
1st. Hello packets must be sent & received.
2nd They must have the same hello & dead timers Also & same Net ID with subnet mask.
3rd They must be in the same area.

When you need a really big window for viewing photos and videos, don't just maximize it: go full screen! This tip works great for viewing photos and videos at maximum size in Windows Explorer or Windows Media Player, utilizing screen space usually occupied by the header at the top of the screen and the taskbar at the bottom. Here’s how:
Open any photo in Windows Explorer, or open a photo or video clip in Windows Media Player. Do one of the following:
*
In Windows 7 and Windows XP, click the F11 key at the top of your keyboard.
The photo or video image enlarges to its maximum size and the title bar and taskbar are hidden.
