Configuring Filter Policies
278 7705 SAR OS Router Configuration Guide
Figure 9: PBR Filtering Based on the DSCP of Incoming Packets
PBR is supported at ingress for the following services and interfaces:
• IES and VPRN service
→ SAP
→ Layer 3 spoke SDP
→ routed VPLS
• router network interface (Global Routing Table (GRT))
PBR is supported on the private IPSec service (VPRN). For more information on IPSec and 
PBR, refer to the “PBR” section in the “7705 SAR OS Services Guide”.

7705 SAR-8 configuration, PBR filter within VPRN commands:
    for DSCP BE
         action forward next-hop indirect 
s_rt1_ip_addr
Note: The static routes created on the 7750 SRs are used solely for directing traffic from the
          7705 SAR-8 via PBR and DSCP bits.
    for DSCP AF11
         action forward next-hop indirect 
s_rt2_ip_addr
7750_SR_1 configuration, VPRN commands:
static-route  
s_rt1_ip_addr
    next-hop  
to_MTSO_ip_addr

static-route  
s_rt2_ip_addr
    next-hop

Note: A PBR filter action can be assigned to an Epipe or Ipipe, or to VPLS (SAP, spoke 
SDP, or mesh SDP); however, the PBR action is ignored (not performed).
