Experts,
I have come to a lost when I am looking at an acl question. I have 4
routers R1 <-> R3 <-> R4 <-> R5 and R5 <->R1 so it makes a big circle. R1
and R4 both run EIGRP and OSPF and I redistribute on both. R3 is EIGRP
only and R5 is OSPF only. In my lab there is a requirement for R1 to go
the long way around to get to R3 Lo0 address 150.1.3.3, so in R1 under the
ospf process I put in.....
router ospf 1
distance 89 0.0.0.0 255.255.255.255 50
access-list 50 permit 150.1.1.0 0.0.0.255
In my workbook it has the ACL should be...
access-list 50 permit host 150.1.1.0
Both ways appear to work, but I do not understand why the host option
works. It has to be some logic I am missing in the ACL, can some one shed
some light on this for me?
Chris
