Book Recommendation

PStefanov

Hey everyone,

I need some advice for some of the topics on the CCIE R&S Lab Exam. I am looking for books (not Cisco Congifuration Guides, I am going to read them anyway, but I need thorough understanding):

• DNS
• SNMP
• AAA
• PPP/HDLC
• GRE
• MSDP

Thanks.

Regards,
Pavel
