It becomes a choice unless dictated.For #3, I think he was talking about using "network 10.10.10.10 0.0.0.0 area 10" versus "network 10.10.10.0 0.0.0.255 area 10" in which case it makes no difference.Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE #153, CISSP, et al.CCSI/JNCI-M/JNCI-JIPExpert VP - Curriculum DevelopmentIPExpert Sr. Technical Instructor

Dear All,As "doubt" on the topic goes, kindly receive my answer:Queries=>1. What will be the approach in lab of calculating metrics for
ospf, eigrp routes when they are redistributing each other? Do we need
to calculate the exact figure or can we go for an approximate?2. What about configuring the mask of loop back addresses of all
Routers and switches as should it be /24 or /32 when the question says
like if unspecified, it should be /24.
3. When ospf area defines, do we really need to go for wild card
mask of 0.0.0.0 or 0.0.0.255 for a class C address? What is the actual
reason sometimes we use /24 or sometimes /32 for the same class C
Network/ subnet?Answers=>1. Accurate figure would be needed/ as it is already defined.2. If not asked or not configured, the loopback always goes to have a mask of /32.3.

Hi Scott
Please answer my questions.
1. What will be the approach in lab of calculating metrics for
ospf, eigrp routes when they are redistributing each other? Do we need
to calculate the exact figure or can we go for an approximate?
2. What about configuring the mask of loop back addresses of all
Routers and switches as should it be /24 or /32 when the question says
like if unspecified, it should be /24.
3. When ospf area defines, do we really need to go for wild card
mask of 0.0.0.0 or 0.0.0.255 for a class C address? What is the actual
reason sometimes we use /24 or sometimes /32 for the same class C
Network/ subnet?
Thanks & rgds
Jay
