Hi all,
I have been given loopback ip addresses 60.50.0.1/16 ,60.100.0.1/16, 60.150.0.1/16, 60.200.0.1/16 and i need to convert them into network address using manual summarization but i have hardly no clue how to do it.
Thank you in advance for helping me.

Hello @hussainabbas1442 ,
convert the loopback addresses to network addresses means find the subnet address of each
example:
60.50.0.1/16 loop0 -------> 60.50.0.0/16 the subnet address has all zeros in the host portion that for /16 are the last two bytes or octets.
please note the EIGRP manual summarization is configured at interface level and will create a summary route that is sent out the interface where it is applied
example:
int fas0/0
ip eigrp 60 summary-address 60.0.0.0 255.0.0.0
Hope to help

not sure what is the context here of your goal
in general you looking manual summarisation as below :
1. you need to disable auto summary
router eigrp ASnumber
no atuo-summary
2. you looking to do manual summary.
ip summary-address eigp ASnumber ip address mask (in your case 60.50.0.1/16 ,60.100.0.1/16, 60.150.0.1/16, 60.200.0.1/16)
is this what you looking, if not elaborate more of your question and requirement.

Hello,
the summary address is:
ip summary-address eigrp X 60.0.0.0 255.0.0.0

Hi @balaji.bandi and @Georg Pauwen,
I was given this to make in Packet tracer but before i design or arrange in Packet Tracer i says to connvert the following into network address so I have no clue for that as well but thank you for the commands.

Hello,
looking at this again, since they want you to convert the loopbacks to'network addresses' (plural), they might just want you to use a network statement for each loopback:
router eigrp 1
network 60.50.0.0 0.0.255.255
network 60.100.0.0 0.0.255.255
network 60.150.0.0 0.0.255.255
network 60.200.0.0 0.0.255.255

As per the information and input we have given right direction, you need to test and advise if anything not working.

The main confusion is do i have to convert manually or the packet tracer will provide the manual summarize with the command

Until IOS 15, EIGRP process did auto-summary by default; we had to turn it off with no atuo-summary under router eigrp. That auto summary was not a good idea; pretty much everyone type no atuo-summary right after router eigrp x.
Finally, Cisco turn it auto off in IOS 15. From highlighted part, I think, they ask to do it manually with ip eigrp 60 summary-address 60.0.0.0 255.0.0.0 under interface level. Looks like your Exercise goal is to learn summarization and how to enable summarization on eigrp
anyway, You should learn enabling it both ways;
