Per "The Complete Reference", page 35, the 603e PowerPC processor on the
PFE control board(FeB,SsB,ScB,SfM) handles:
- ICMP unreachables such as TTL expired
- Rate limiting traffic over fxp1 to RE
- Exchange control traffic w/ RE
Per page 12, exception packets sent to the RE include network control
and local delivery:
- Routing protocols
- Local Delivery (ie. ftp, ssh, telnet, dns, ntp, radius, tacacs,
etc...)
- Packets with IP options

As far as I know, TTL expired packets are handled by the PowerPC.
