I have used the following method to get close to production LD delay:
ip vrf 1
rd 0:1
ip vrf 2
rd 0:2
int tun 1
ip vrf forwarding 1
ip add 10.0.0.1 255.255.255.0
tunnel source 5.0.0.1
tunnel destination 5.0.0.2
ip mtu 1500
int tun 2
ip vrf forwarding 2
ip add 10.0.0.2 255.255.255.0
tunnel source 5.0.0.2
tunnel destination 5.0.0.1
ip mtu 1500
int loop 0
ip add 5.0.0.1 255.255.255.0
ip add 5.0.0.2 255.255.255.0 secondary
Note:
1. int loop 0 ins not included into any vrf
2. default ip mtu for a tunnel = 1490. ip mtu 1500 fixes that
Routing within:
router eigrp 100
address-famuly ipv4 vrf 1
network 10.0.0.0
no auto-summary
autonomous-system 100
address-famuly ipv4 vrf 2
network 10.0.0.0
no auto-summary
autonomous-system 100
etc.
Debug:
sh ip route vrf 1|2
ping vrf 1|2
sh ip eigrp vrf 1|2 neigh
etc...

Hi GS,
I don't believe this function exists at all, but just to double-check,
in case I missed something simple.
Background: Delay insertion was desired in a lab environment to
simulate production network delay form City A to City B.
Thanks!
