IOS Router

1. create access-list for packet filter
access-list 1 permit 10.100.1.45
2. create buffer
monitor capture buffer holdpackets
3. filter buffer
monitor capture buffer holdpackets filter access-list 1
4. create capture point
monitor capture point ip cef mytrace all both
5. associate capture point with buffer
monitor capture point associate mytrace holdpackets
6. start capture
monitor capture point start mytrace
• Look at progress
show monitor capture buffer all parameters
• See list of capture points
show monitor capture point all
7. Stop the capture
monitor capture point stop mytrace
8. Export buffer as PCAP
monitor capture buffer holdpackets export tftp://10.1.10.27/mytrace.pcap
9. Remove buffer
no monitor capture buffer holdpackets
10. Remove capture point
no monitor capture point ip cef mytrace all both

Configure NAT in the VRF lite scenario

Configure NAT in the VRF lite scenario
But, why would you do a VRF and then decide you wanted to route from that VRF to your global routing instance?  And why on earth would you want to NAT between two interfaces in different VRF's. 
Well, I did end up needing to and this article was very helpful.

ip vrf MyVRF
 exit

interface 
 (no switchport)           ! make routed port
 ip vrf forwarding MyVRF   ! associate interface with MyVRF
 ip address A.B.C.D M.M.M.M

interface 
 switchport
 switchport trunk encapsulation dot1q
 (switchport nonegotiate)
 switchport mode trunk

vlan 10
 name WAN-VLAN

interface Vlan10
 ip vrf forwarding MyVRF
 ip addr E.F.G.H M.M.M.M
 ip nat enable

! now the VRF-aware NAT config:
interface 
 ip nat enable

interface Vlan10
 ip nat enable

ip access-list standard LAN-to-NAT
 permit 

ip nat source list LAN-to-NAT interface Vlan10 vrf MyVRF overload

! finally the def. route
ip route vrf MyVRF 0.0.0.0 0.0.0.0 

Cisco IOS

We used to have to pay more for the IP Advanced version of IOS to run OSPF on our branch office core routers.
Now I am told that we can run at least one instance of OSPF in IP Base license (cheaper) when running IOS ver 12.2.55se1
