DF bit Clear

[sameer.shah]

Hi

Any one knows hows to clear df bit in IOS-XR from interface.. we used to do it in IOS as follows:

interface xxxx

ip policy route-map CLEAR_DF

route-map clear-df-bit permit 10

match any

set ip df 0

We need to apply same for ASR running IOS-XR 4.2.1

This is not about PBR support on ASR, We need to know option of clearing DF bit from IPv4 packet

hi Sameer,

PBR is not currently supported on the ASR9K. Have a look at ABF alternatively:

http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.2/addr_serv/configuration/guide/b_ipaddr_cg42a9k_chapter_01.html#con_1158105

What is the use-case on the ASR9K as it doesn't do PBR ?

regards,

david

Sameer,

This is supported in 5.1.0.  Here is an example of the config:

ipv4 access-list allow_acl

10 permit ipv4 any any (cfg)

class-map type traffic match-any df_class

match access-group ipv4 allow_acl

end-class-map

policy-map type pbr df_bit_policy

class type traffic df_class

set ipv4 df 1
