[OSL | CCIE_RS] some doubts - please clarify!

[Jayagiri B Nair]

Hi Scott   Please answer my questions.   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? 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. 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       Note: This e-mail (including any attachments) is intended only for the recipient(s) named above.
