It would appear that the section was reworded at one time. Without restrictions on the spokes with regards to frame maps, PBR is not required.
Let's take a look at this scenario: (slightly different) Hub with a map for each spoke. Each spoke with only a single map pointing at the hub allowed. The problem that arises here is spoke to spoke communication. There are some miscellaneous workarounds. If OSPF was used, a point-to-multipoint topology would have each spoke advertise a /32 for the local endpoint, and other spokes would receive this and have a route for the spoke /32 reachable via the hub. Policy routing - In addition to applying on the non-frame interfaces, apply locally with "ip local policy route-map xxx" if you want your router to be able to ping those networks. Construct an ACL, and match in a route-map. Access-list 101 permit ip any xxxx yyyy, where xxxx and yyyy are network/mask for subnets connected to the other spokes. Route-map TEST Match address 101 Set ip next-hop z.z.z.z (where z.z.z.z is the hub address) Marvin Greenlee, CCIE #12237 (R&S, SP, Sec) Senior Technical Instructor - IPexpert, Inc.

I'm waiting for my upgrade to the "blended learning solution" package to arrive this week. In the meantime I'm having a problem with Lab #20 in the old workbook. It has a Frame Relay network set up with a hub and 3 spokes. No subinterfaces are allowed and only the Hub can have frame map commands. The Proctor guide recommends using PBR, but when I look at the "final configs" for R2, R4, R5 & R5 none of them have PBR configured on them? Is this a typo? Also, how do you go about using PBR in the place of a Frame Map command? Since PBR can only be used for inbound traffic do you set up your "ip policy" on the non-Frame relay interfaces of the spoke routers? Thanks, Mod.
