Figure 9 Pbr Filtering Based On The Dscp Of Incoming Packets - Alcatel-Lucent 7705 Configuration Manual

Configuring Filter Policies
PBR is supported at ingress for the following services and interfaces:
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
for DSCP AF11
action forward next-hop indirect s_rt2_ip_addr
2 7750_SR_1 configuration, VPRN commands:
static-route s_rt1_ip_addr
static-route s_rt2_ip_addr
3 7750_SR_2 configuration, VPRN commands:
static-route s_rt1_ip_addr
static-route s_rt2_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.
• IES and VPRN service
→ SAP
→ Layer 3 spoke SDP
→ routed VPLS
• router network interface (Global Routing Table (GRT))
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).
