iewb sp vol2 lab3

1. EIGRP - should investigate more
2. redistribution eigrp-->bgp-->rip
3. central services vpn
4. unicast rpf - it is designed for rtbh :)

iewb sp vol2 lab 2

1. it is good to memorize whe to find working example in univercd
2. passive interface under isis process adds interface to the process (not needed to add (ip router isis)
3. ospf can declare link is down by using fast hellows
4. ip nat is always fun
5. ip route always helps
6. frame relay shaping has only one formula. but it is not easy to remember
7. ospf sham links:

• loopbacks used for sham link endpoints must be advertized using BGP (not ospf)
• when mutual redistribution is in place - check that loopback address is not redistributed from ospf to bgp and back

IEWB-SP-VOL2 Lab 1

1. tricks changing default ospf network type on interface (point to multipoint and brodcas)
2. ospf md5 authetication will not work if no key with number is specified
3. mpls TE sometimes not working after interface default ospf network type change
4. for VRF aware NAT do not hessitate to put nat inside statemen on P facing interfaces and define route-map very precisely
5. ip mroute helps to avoid mess introduced in unicast routing after mpls TE tunnel is up
6. always test mcast, provide mroutes to RP
7. QoS - what a mistery :)

OSPF spam-link

link to CCO

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ospfshmk.html

one special note: loopback ip address used for spam link source and destination must be advertized via MP-BGP (redistribute connected of network statement).
If ip addresses will be advertized using ospf you sham link will be flaping countiniously.
